I use manual with auto ISO almost 100% of the time. With modern cameras, ISO is my least important setting. I use EC to adjust for backlit or other tricky light. For me, the wrong shutter or aperture can ruin a photo. I can work with some fairly high ISO if shutter and aperture is where I want or need it. YMMV.
This is a simple and straightforward explanation of the reason and benefit of using auto iso. I use it almost always and love it. Auto iso has allowed me to enjoy my photography even more. I also use Fuji and shoot jpeg 100% of the time. Having more fun shooting instead of spending all that time post processing.
