I picked up the DA V2 mini on sale, it's great for a M size hand with a claw or finger grips (so works very well for me) and was very glad to see it has the new optical switches - it's very good for twitch games since it's so small and light
I have 2 Logitech mice (a G-pro and a G203) that both have dreaded double-clicking issue in about a year of use - looking at the G402 and after a quick search, just as many complaints and guides to replace switches - they apparently use the same omron switch that has the china OEM model as the ones I have. That being said, the g402 might work better since it's a bit larger, depends on your hand size and grip
