I like when maps have memorable patterns or structure that makes the map look like it's fun to flashlight, well placed spinners (spinners at the start of a map are the worst), well flowing high velocity sliders, jumps with triple stacks, simplicity with heart, and when there's room to breathe (not by break time).

I'm not a fan of freeform, high AR (like a map of 140bpm 1/2 notes being AR9), sliders not meant to be perfectly followed, maps that value creativity over playability (not including auto map art), half of alt-style maps nowadays, majority of 1/4 slider jumps, and most modern normal difficulties (I feel REALLY bad for new players stuck with maps that are basically slow sliders into slow sliders into maybe a note with like no spacing or structure).

I find it very hard to finish maps because I'm my own worst enemy. I can never accurately put my visions into the map, or I'm too much of a perfectionist to move forward. Even if it's not my cup of tea or not super high quality, I respect the drive some players/mappers have to be able to pump out a map. Because of this, I very rarely think a map that goes through the ranking process deserves under a 2.
