I suppose I'm somewhat good at doing _some_ easy maps with all mods (not perfect), since I have a few top 50s, all with easy maps. Though flashlight for me is quite hard; I prefer HD/HR/NC. I'm bad at high bpm, >8 AR (yeah I'm relatively new to this game) (I've done 1 or 2 AR 9 songs nomod, with pretty bad combo), long streams (both 1/4 and 1/2, if 1/2 is considered stream), and small circles. I play HT on very hard songs, which is probably bad for me, but at least I get to feel good about doing Freedom Dive another.
I play mouse-only so i'm best with anything 120-200 bpm that is mainly jumpy. I can do screen jumps just fine, surprisingly. However, streaming is a huge problem (i can guess, probably for all mouse-only players?). I run out of stamina on any song with streams that is longer than 2:30. Maps with snaky streams like Chase the Light are also really difficult for me to play.
Best: Ar 10 maps with jumps and streams between 190-210 bpm Worse: Ar9 maps with high bpm and jumps, e.g Atama no taisou, Heterodomia (or whatever the fk), I´m Horrendous at maps where you have to tap fast but have to snap to the notes at a "slower" pace im good at hitting them mostly when they come up one by one (ar10). Anyway this is what im working on...
Best? Probably rhythm intensive and streamy maps. Worst? Anything with a particular pattern repeated without any changes to it, especially jumps. When I say repeated, I mean like used so frequently you basically know the map for that... https://osu.ppy.sh/b/374472 <- Squares, nothing else.
