I converted to Mac 5 years ago and love it. One thing that will happen if you join the Apple world is all of your photos will be shared across all of your Apple devices automagically (Mac, Ipad, Iphone). Apple is more expensive --- don't know about slower as Gene51 says I haven't experienced that -- but so much better than Windows in my experience. Updating is a breeze and none of the other Windows weirdness that seems to come with every PC (blue screen of death, endless updates, etc.)
It's only slower if you are at the same price point - for example, a 27" iMac with Retina 5K, 1 TB SSD, 3.6 GHz 8 core i9 cpu (boostable to 5 GHz), 32 gb DDR4, and a Radeon Pro 580X with 8 GB Vram, will cost $3600.
You can get a comparably equipped Windows machine with the same CPU (presumably an i9900K Coffee Lake), 2x16 gb DDR4 ram, same graphics card, and an m.2 1 TB SSD for $1950. Add an LG 27MDSKA B 5K display for another $950 and you have a more or less equivalent system to the iMac for $2900
There are a couple of differences that are worth noting - the iMac, may have all memory banks filled with 32 gb, so upgrading memory is likely to involve replacing what is in the machine, as opposed to simply adding more memory modules.
The 1 TB SSD in the iMac is not an m.2 NVMe drive as it is in the Windows machine - it is likely a SATA III drive, since it appears to replace the baseline Fusion drive, which is also a SATA III drive. The m.2 in the PC is 4x faster - which is important if you are using it to boot from and run programs on, as well as keeping a Lightroom catalog on it.
The 5K display may be stunning, but you are, in part, paying for a 500 nit display when you won't really ever use that much brightness for photo editing. Also if you use the full native resolution, font scaling will be necessary, and you give away some of the high-res benefits in doing so. My personal preference is not very high resolution screens - UHD at 3K is more than enough for photo editing, and using two displays is easier on the eyes. I use a pair of 24" HD displays that provide 3840 px horizontal resolution c 1280 vertical. The extra real estate has definite benefits over a single very high res screen.
The only GPU offerings are AMD's Radeon 580 or 48 - both are great for gaming and video, but offer little in the way of performance benefits for photo editing. But given the 5K display, you still need a high performing GPU if for no other reason than to provide snappy refresh. With the PC you can select ANY currently manufactured graphics card from NVidia or AMD, with the performance edge going to NVidia in most cases.
The PC can be upgraded internally to include (2) m.2 drives, (4) 2.5" drives and (3) 3.5" drives without requiring a bookshelf full of external drives. Apple's solution requires external drives to update storage, making expansion expensive.
If I were to add additional internal storage to the PC configuration above, I could add a pair of 8 TB drives for a total storage of 17 TB and at a cost of $600, and still be cheaper that the iMac.
I could also go the other way and build a faster computer with more cpu cores, more storage and faster graphics and still be less expensive.
So I stand by my original premise for the same money spent - an iMac will not be as fast as a PC. If you equip the two machines with the same hardware (as close as possible), the PC will be considerably cheaper - in this case by $800.
A good resource to use as a guide comes from Puget Systems in Washington State, halfway between Seattle and Tacoma. They've been building customized photo editing systems for years, and they actually publish their benchmarks and results of their testing for all to see - unlike Apple which just tells you how wonderful their machines are.
And another British systems integrator, Chillblast, provides a comparison between Mac Pros and PCs here:
https://www.chillblast.com/photo-editing-mac-vs-pc.htmlWhile it is not as unbiased as the Puget Systems comparisons, the performance vs price analysis is pretty much consistent with Apple providing less "bang for the buck" that is widely understood by those outside the Apple community.
The other bit of mythology is the Mac resistance to viruses. It has more to do with being an easy target and sheer number of users than it has to do with the Apple OS being virus resistant. An interloping writer of malware is going to go after the giant school of fish that the PC community represents with its 87% market share long before they go after the 13% Apple market share. For them the ROI is better with PCs when they discover and exploit a vulnerability. There was a time when the OS used in Apples very secure, being based on Unix and running on Motorola cpus, but those days are long gone - yet the legend persists.
If you want anecdotal stuff - I built a machine in 2011 and it has never been infected with a virus. I've had a heat issue from mild overclocking (I added a liquid cooling system) and another from cat hair clogging up the screens in front of the fans and reducing airflow that required some reboots until I figure out what the problem was, and the thermal heat-transfer compound I used to seat the cpu onto the heat sink became ineffective after 6 yrs requiring a reapplication (I used a better compound) - otherwise, the system has been flawless. Needless to say, I do not use this machine for much else outside of photo editing and posting on some forums like this one, and GMAIL and some internet browsing. I am pretty careful to not fall prey to suspicious emails, messages and other delivery vehicles for malware, so by not visiting places where I may pickup a virus I am sure this has helped keep my system free of bad stuff. My nephew, in college, brought me his computer which couldn't even boot because of the literal hundreds of popups. A half an hour later I had cleaned his system and he was back in business. I told him he needed to stop visiting porn sites, or he would be on his own the next time this happened. We both had a laugh.
