Best mouse I've found is the Logitech G Pro, it annoys me that it's full of stupid RGB lights, but it has the precision and speed of a good gaming mouse without being too ridiculous in design or cost ~$60
That Logitech mouse shape is basically perfect. I've been using mice with that body profile for 15 years now. I periodically check up on the newest iterations to have my replacement bookmarked, but this decade old one seems content to keep chugging on.
I use a Logitech G502 and it's great. This is the second one I've had (spilled drink on the first one, RIP) and I'll buy the same again when this one dies if they're still around.
