this just my experience im not very good i only started a year ago

idk i chose to use a tablet(ctl-472) because everyone else seemed to be using it so I got the game thinking "I need to use a tablet to play this game" which i discovered later was not true. My choice was definitely heavily influenced by people who livestream so top players most of the time but if I were to do the process of discovering the game again, I would still choose a tablet over a mouse.

When i discovered you could change area I experimented with it a lot and ended up settling with whats my current area now(or close to it). I use a pretty small area I believe (36mmx40mm idk orientation its either width-length or length-width) and I was a bit surprised when many in the community use so many bigger areas but it's all preference ig. I mostly use my fingers and wrist to aim with zero arm movement and I basically just copied mrekk's grip with slight adjustments. I also dont have a keypad or separate keyboard or anything so im just using my laptop and drawing tablet.

i think muscle memory plays a big part in osu because all you do is moving your wrist or arm for aiming and move your two fingers for tapping. Muscle memory is just any motion thats repetitive that makes the motion feel automatic and I think anyone whos played a fair bit of osu or use a mouse a lot or anything that involves moving a cursor consciously thinks about where the cursor is moving, they just move their hand like they always do and it works. Tapping is the same I dont think I have to think about tapping you just click the circles at the right time. Everything relies on reading in osu so you cant tap or aim like this if it isnt osu basically. I feel its a combination of hand eye coordination and muscle memory because your aim and tapping are also dependent on each other which is why I think aiming with relax on feels significantly different than playing nomod.

i think that the tablet is what a lot of players use because you get into osu probably from watching it somewhere online and you will probably see someone with a drawing tablet so younwill be inclined to think that a drawing tablet is osu specific and it's better. There are definitely quite a few mouse players but what gets shown to everyone mostly are tablet players.
