Before you look at a single review — including ours — it's worth knowing your actual grip style. Shape recommendations are only useful once you know what you're matching them against, and most people guess wrong on the first try.
The three grip styles
Palm grip: your whole hand rests on the mouse, from fingertips to the base of your palm. You get full contact with the shell, which favors mice with a defined rear hump to fill that space.
Claw grip: your palm hovers slightly above the rear of the mouse while your fingertips arch down to press the buttons. This favors mice with a more pronounced front slope and a lower, shorter rear.
Fingertip grip: only your fingertips touch the mouse at all — your palm never makes contact. This favors light, short mice that don't punish quick, hovering flicks with excess weight.
A quick way to test yourself
Rest your hand on any mouse you currently own, in your normal gaming posture, then lift your hand straight up an inch without changing its shape. Look at what's still touching an imaginary surface below your palm:
If your whole palm and fingers would still be resting flat, you're a palm gripper. If only your fingertips are down and your palm is clearly arched above the surface, you're fingertip. If you're somewhere in between — fingertips down, palm hovering but close — you're claw, which is the most common misidentified grip because it feels similar to palm at first glance.
Why this matters more than any spec sheet
A mouse with a great sensor and a shape that fights your natural grip will always feel worse than a mouse with an average sensor and a shape that matches your hand. That's the whole premise of this site: shape is the first filter, not the last one.
What to do with this information
Once you know your grip, start with the reviews tagged for that grip style rather than the highest-scoring mouse overall. A 9.0-rated mouse built for claw grip will likely feel worse in your hand than a 7.5-rated mouse built for palm grip, if you're a palm gripper.
