I was like you. Both are great your over thinking it. 575 I think has a slightly less rounded curve but trust its nothing to worry about. I swap between both with ease. Matter of fact. I love the 570 sometimes but my hand arch started to get worn out after hours of use. 575 has less of an arch and relaxes the wrist a tad more.
I got an MX Ergo. It’s godfuckingawful. The M570 looks back at you so your thumb rests forward of the centerline of the ball. The Ergo looks to the side like a lobotomized beluga so your thumb rests on the centerline of the ball reducing the comfortable range of vertical travel. It also developed a nasty case of leprosy, the skin started to blister and peel, so rubber wrapped devices from Logitech are dead to me forever. I just…I’ve been soldering new click switches into my little herd of 570s because Logitech is really bad at electronics and they used inappropriate switches that wear out prematurely so I’ve been fixing it instead of buying anything else from them because I am a severely petty man but they’re starting to fail in ways I don’t know how to fix.
I’ve got a bad right click on my 570 and it’s years old. That’s part of what caused me to get a 575. That and work I needed something good rather than a traditional mouse.
Edit: get a 575 you will make concessions but given your ergo trust me it’s worth doing. Retire those 570s!
I’ve been using trackballs for 25 years. What do you think of the M575? I’ve got a fleet of old and tired M570s that will need replacement soon.
