With some cursory scripting, and "only" 16423 of the comments (My browser didn't load any from longer than 7 hours ago when sorting by new) which specified just the number (no text, no decimals, etc (included enough & massively simplified the scripting)) there is at least 1 of every number already.
Ergo no-one here will win (there is just 1 prize) but I might as well say the most common numbers:
206x 777
206x 69
187x 2
170x 666
167x 420
144x 7
121x 3
105x 1
99x 888
95x 4
And the least common (these are the only ones with 1 result):
1x 966
1x 960
1x 948
1x 903
1x 90
1x 807
1x 608
1x 580
1x 440

I don't think this is a collaboration with the subreddit (just hosted on it), so it might be best to say that the host is Marvo Z instead of PCMR.
20k comments though… I'd be surprised if there's one whole number not said yet.
