I have the Attack Shark x3 pro, it's a good budget mouse (I live in Argentina and getting the g pro superlight is like 160-170 usd which is A LOT), the clicks will be heavier than the g305 though and you may need to adjust (I come from a g203 since like 2019 lol).
Overall I like the mouse, so far I had some micro stutters with it wirelessly but I live in area that the 2.4ghz band is really used up so it isn't a mouse problem. try getting a new version of it, older models have some connection issues I think
for you, coming from a g305 will need you to get used to this one, it is like 3 times lighter, the mouse clicks will be heavier (you won't notice it in valorant but maybe in something like minecraft for example) and the scroll wheel is a little bit worse but it's fine
