I can’t speak to either of those specifically, and maybe things have changed recently, but several years ago, I went through a period where every single Logitech mouse I bought (4 of them, various gaming models) developed a double-click when single-click was intended, each of them after about 6 months or so. And I had been using Logitech exclusively for many years up until then, so giving up on them was a difficult choice.
I eventually dropped Logitech mice because of this problem, and switched to a Corsair M60 about 5 years ago. That M60 is still functioning perfectly to this day. I love it so much that I bought a spare, which I have never needed to take out of its packaging.
Some people find the 502 comfortable, but I do not like mice that force you to grip it in a specific way. It’s bad design and guaranteed not to work for everyone.
Unless something better comes along, or some real improvement is made to the mouse I have I can’t think of any reason not to stick with my zowie mice.
Simple safe shape, good sensors, and no annoying drivers to deal with.
I’m using a DeathAdder 3.5 and I like the mouse itself a lot. I came from a Logitech MX518 and I’d say I like them about equal. I preferred the mouse wheel of the 518, but I prefer the side buttons of the DeathAdder. The shape of the 518 was slightly more comfortable, but I like the materials of the DeathAdder a little better. Durability wise I couldn’t yet say, since the 518 still worked perfectly well when I replaced it, and it was probably going on 7 or 8 years old. The sensitivity buttons are obviously far more conveniently placed on the 518, but I never use them anyway so I actually prefer them not being in my way.
I would prefer not having to run mouse software at all, so that kinda irritates me, but it’s not a big deal. Synapse seems to have some nice features for those that would utilize them.
You don’t need to run any software with the G502, as you can save all the settings in the mouse itself. You lose program-specific settings of course, if that matters to you.
I’m still a fan of the Deathadder. After my last one starting having trouble, I seriously looked for an alternative (see upthread), but in the end just came back to the Deathadder, as nothing could quite fill its big shoes.
(or perhaps I’m just too used to it now and as a cranky old person don’t want to change my habits after almost a decade using this mouse…)
I’m a fingertip gripper myself, but my main mouse CM Storm Xornet is supposed to be a claw grip mouse. It’s very old, and even its successor Xornet II is not made anymore. But hey, if you’re looking for claw mouse…
I hated the Razer software and my Razer mouse broke too young, so I’m done with Razer. Logitech has always been good for me, hopefully they don’t go downhill.
I won’t buy anything from Razer again either because of their issues with using cheap glue to secure rubber parts, though that lever does look nice. I love my Func MS-3, but they no longer make it. It has a button like that, but my tiny hands can’t reach it, so that lever does make sense.
