I really like 咲, idk why but it just looks really like something blooming. It might have to do with 同期の桜 (doki no sakura) A Japanese war song about unity and having a blossoming friendship until becoming kamikaze piolets and dying together for the greater good (at least I think that's what it means anyway).
I like 亻(radical form of 'person') since my mnemonics with it always use a specific person and I always put them in goofy situations.
The kanji I like to write the most is 隹 (I use the keyword 'turkey'). Very satisfying and easy to remember stroke order compared to other kanji with comparable number of strokes.
Purely from a design perspective I love the kanji 殺, the way the four small radicals are neatly arranged in a square. (Is it weird to say you like 殺, I still wonder though.) The picturegram-style kanji I probably appreciate the most is 桜, where the little petals of the tree seem to be floating down over the figure of the lady. It's just perfect.
