G3 V2 Pro

Agree with another comment, the g3 is the safest bet, same shape, better tech, virtually no downsides as it's also pretty cheap. I'd stay away from a new g305 since it's heavy and you have to keep buying batteries. Also steelseries mice in general are pointless, much better tech exists for the price. The X3 and R1 are pretty well reviewed but the hump will be higher profile, so be wary if you want to experiment.

Zaopin Z1 Pro Max looks good. I never tried it but read good things. I have had good personal experiences with the Fantech Aria XD7. The Fantech Aria II is the most recent model of said mouse. The Mchose g3 v2 pro looks nice also which is a clone of an egg shaped Logitech mouse if I remember correctly. I currently main a different MChose mouse and it’s pretty great quality-wise I wouldn’t worry too much about the occasional negative review. The Chinese brand mice are really good all around. Most negative mouse reviews on here are nitpicking- which is to be expected from enthusiasts

MCHOSE G3 V2 has a good implementation of PAW3311, but at the right price go for G3 V2 Pro PAW3395. VXE R1 is a similar situation; go for the PAW3395 model R1. Pro has coating & Nordic MCU power efficiency. Attack Shark X3 unfortunately I can't recommend. Go Kysona Aztec (M600S) / M600 V2 both solid firmware.

I have an Mchose G3 V2 that I really like. I've heard people say the VXE R1 is better though, not sure.

If you really want a AA battery operated mouse, look at the Logitech G304. If not, I have an Mchose G3 v2 which is the exact same shape (ambi). It's very comfortable for casual use and light as well. Great for gaming too!

if you want a comfortable mouse i definitely recommend mchose g3 v2 pro(its egg shape similiar to logitech g305) if you play longer session of games it has a good specs on it too and budget friendly not too expensive
