I'd put myself at beginner level, shooting on occasion for the last two years. Probably film for the last year especially once I started doing my own home development/scanning
Digital keeper rate is probably 5% if I'm being optimistic.
35mm film is maybe 10-15% but it varies by roll
120 film (both 6x6 and 6x9) I haven't shot enough of in order to figure out yet. I have a few that I like but I'm trash at DSLR scanning, inverting, and fixing them
That's tough... it's probably a tie between my AI-S 105mm f2.5 and 50mm f1.8 Series E. I recently picked up a 50mm f1.2 but I haven't had an opportunity to really try it out between working two jobs, a social life, and winter coming up (Evenings getting darker much quicker)
