To answer your question in two words, HECK YES!!!
In 2015, I needed a single camera for both stills and video. dSLRs were clunky. So I took Will Crockett's advice about Micro 4/3. He loaned me a Lumix G3 and a few lenses for a couple of weeks, and I knew it was close to what I needed. But it wasn't enough.
I tried that original OM-D E-M1 (now known as Mark 1) and I found it to suck mightily for what I do. The thing doesn't fit my hands, the controls are in weird places, or worse yet, buried in menus that are annoying. The video was mediocre, and I needed a well-balanced hybrid (stills plus video) system.
I bought another Micro 4/3 camera, the Lumix GH4, instead. I have loved it ever since, although not for sports or wildlife, since it has CDAF with DFD (Panasonic's "contrast detect autofocus with depth from defocus"). For what I do, documentation, portraits, events, street, copy photography, camera scanning film, and especially video, it is great. The Lumix GH6 was tempting, but after Panasonic introduced their full frame S5 Mark II L-Mount camera with Hybrid Phase Detect Auto Focus, I'm deliberately holding out for a GH camera with PDAF.
Meanwhile, both Olympus/OM Systems and Panasonic have released a lot of Micro 4/3 gear that is dramatically better than the OM-D E-M1.
From Olympus, the OM-D E-M1 Mark II and Mark III are substantially better. The OM-D E-M1X is a sports and wildlife camera. The new OM Systems OM-1 is an evolution of all of those, and gets rave reviews from both die-hard Olympus fans and new users alike. Ergonomics, speed, handling, AF, IBIS, and so many other features are all way beyond what you have.
From Panasonic, the Lumix G9 is a bit old at this point, but is a match in many respects for the OM-D E-M1 Mark II and III. It's a great camera for just about anything but action, since it has CDAF. A recent firmware update brought many of the Lumix GH5's video features to the G9.
The current Lumix GH5 II and GH6 are both true hybrid cameras, about equally adept at both stills and video. The GH6 is arguably the most advanced video camera you can buy for under $2500 (New, it's now priced about $1700).
If I had to buy a Micro 4/3 camera today, for anything involving action, it would be the OM Systems OM-1. But since I record both stills and video, it would be the GH6.
There are tons of independent review videos on YouTube, and if you can jump on DPReview.com before April 10 when they shut down, you can find detailed reviews of all Micro 4/3 models there.
Check out used gear at KEH.com, MPB.com, UsedPhotoPro.com, and of course, B&H and Adorama. There are great prices on most models.
