Especially put against some of the pre-10 packs, this is a great set, and it's really boosted by the presence of some veteran DM mappers and players. Lots of quality towards the end, and lots of shitposting up front.
MAP01 (It's shit but probably should be last map for poetic reasons)
MAP02
MAP03 (so so?)
MAP09 (maybe?)
MAP10
MAP13
MAP15 (maybe)
MAP18
MAP23 (pretty good, not sold)
MAP24 (I love this, debatable if it's actually good)
MAP27 (good, doesn't make the cut)
(most of the UD stuff at the end of the wad is good too but doesn't stand out)

32in24-3
This is really rough in general. The very few shining stars mostly come from veteran mappers.
MAP13
(these lazureus maps are really interesting but don't play well)
MAP23
MAP28 (maybe)
MAP31


32in24-5
The detailing other people's maps concept was interesting but was only really pulled off successfully a couple of times. It feels like sometimes detailers over-invested in shitty maps, or good layouts were ruined by poor detail.
MAP01
MAP05 (maybe)
MAP20 (maybe?)
MAP21
MAP22
MAP23 (maybe)
MAP29 (looks really cool, doesn't play great)

32in24-6
Lots of mediocre maps, boxy with poor height variation.
MAP02
MAP32
MAP21 (maybe)
MAP25 (maybe)
MAP29 (maybe)
MAP45 (top tier jokemap)

32in24-8
The concept of using existing SP maps from the core game really fell flat here.
NONE OF THESE (maybe the jokemaps but even still)

32in24-9
The first more than half of this was absolute fucking drudgery, and it all comes from very very new people to the community, many of whom didn't stick around. It does get appreciably better in the second half.
MAP28 I guess
MAP34!!!
MAP38
MAP40

32in24-10
Huge jump in overall quality on this pack, although there are fewer amazing stand-out maps. You really see a lot of folks getting their feet here for what they might do later on.
MAP01
MAP02 (maybe)
MAP09
MAP10 (Maybe)
MAP15 (maybe)
MAP19
MAP21 (maybe)
MAP24 (maybe)

32in24-11
Yet another huge jump in quality from -10, there's a lot more standouts here from both a graphical and gameplay perspective. A thoroughly playable pack end to end with very few exceptions.
MAP01 (maybe)
MAP02
MAP03!!!
MAP05!
MAP06 (maybe)
MAP09 (maybe)
MAP10 (maybe)
MAP16 (maybe but the name is too funny to not put in)
MAP25
MAP32

32in24-13
Very solid pack, not quite as good overall as -11, but a lot of genuinely hilarious maps that are very worthwhile
MAP01!!!
MAP07
MAP08
MAP09
MAP17 (probably!)
MAP31 (maybe)
MAP42 (maybe)

32in24-15
This one's quite good too, on par with -13. Also was I just completely absence during everything but the picture and concept phases on this one? Cause I hardly remember any of these maps, though there are quite a few good ones.
MAP01 (Maybe)
MAP03
MAP04
MAP09 (probably)
MAP20
MAP25
MAP32 (maybe)
