Many people use drawing tablets to play osu. More here: Gaming with a drawing tablet
If you are interested in playing osu with a drawing tablet, then do not rely on recommendations from drawing tablet reviewers. They focus on the needs of the creative users. Don't rely on my recommendations for the same reason.
Instead, the definitive resource to consult is Kuuube's tablet buying guide.
If you do want a quick answer now though, these two tablets are excellent for osu.
One by Wacom Small (CTL-472)
One by Wacom Medium (CTL-672)
You could also buy one of these tablets below, which are also great for osu, but they are very expensive and are not any better for osu than the ones listed above.
Wacom Intuos Pro Small (PTH-460)
Wacom Intuos Pro Medium (PTH-660)
Wacom Intuos Pro Large (PTH-860)
Wacom lists recommended tablets for osu here: https://estore.wacom.com/en-us/osu. However, they list some tablets that are NOT recombed for osu. So, I recommend you disregard their list andpick from the models listed above or the one Kuuube recommends.
