I may format this post better at a later time, but for now I will include a bit of personal experience : I see a lot of people often ask "what is the best gaming mouse that I can buy", and it is really a difficult question because there is no best mouse, only the best mouse for you. One thing I strongly believe is that one very important factor in a mouse is it's weight. This is a common reason as to why wireless mice are looked down upon, despite their ease of use they simply weigh so much more. One mouse that comes into mind is the new Ultralight Pro from Finalmouse. While not being the best looking, it has a "honeycomb" shaped body with multiple holes in it to reduce it's weight as much as possible, bringing it to about 70 grams, making it very easy to move quickly and "control" flicks with it. Pairing it with a top of the line sensor and I honestly think it's the best mouse on the market right now. But I could never use it, and that's because of it's size. Being a very small girl, I kinda just naturally come with very small hands. This is where the where the F-U.P. really.. f ups for me :^) it's way too big. Sadly this makes me unable to use many of the better mice on the market, such as the G403, DeathAdder, and Rival 600. This really starts to limit my search, as there are not very small mice available. Narrowing it down to low weight, small mice, I start looking at the Logitech GPRO, a few Zowie mice such as the FK2, ZA, and ECA1, along with some lesser known companies such as Ninox. This is where shape really starts to play a big role. After trying these mice in hand, I found that the ZA had a very large "hump" that made it feel better for a palm grip, but as I have a weird "hybrid" grip that I would say is a mix between a fingertip and claw, I hated it. With this grip on the FK2, I found the mouse to be too "long" as the front of the mouse would often hit my palm during vertical movements, messing up my momentum and making me mess wildly. What really worked for me however, was the GPRO, with what seemed like a very "safe" shape, it didn't fit my hand exactly "naturally" at first but it did fit perfectly, and overtime has become my favorite mouse after considering many of these key points. Other things factor in too, such as build quality, having at least a decent sensor that is competitive with top of the line sensors like the 3360, and where macro buttons are placed / scrollwheel / mouse feet / etc. This is where the gpro fell short for me, it had a very thick and heavy cable in contrast to the light and amazing cable with Zowie. I found a fix in this by buying a Paracord cable and replacing it through a mod. I also put on new mouse feet as the stock ones sometimes feel like they could glide just a bit better, and that is how I found my perfect gaming mouse.
