Okay yeah, some of these I still don't quite recognize or know well (have I even played a single match on them!?), but:
Colony is fantastic, absolutely brilliant for parkour with Stim. One of the coolest to stomp around in as a Titan too- great sense of scale.
Corporate is one of my favorites. The center area with the statue is epic for multi-Titan battles and firing Triple Threat grenades into the little tube corridor windows, oh, my word.
Training Ground is great, wonderful for CTF. It has the most deliberate "this is a map for a videogame, not a real environment" feel, but that sort of makes sense because of what it is too. The building features where you can be in the tunnels underneath the grating and shoot upward are lovely.
I actually really like Airbase, for whatever reason I perform pretty well in the hangars.
I don't feel comfortable with really any of the others enough (or even feel sure of which they are) to comment on how much I like them. This isn't because they are unmemorable or indistinguishable, but because of mechanical limitations:
1) When playing campaign it doesn't seem show the name... at all. The matches have mission titles ("Here Be Dragons!") and while these are fun and all I really don't need to be reminded of them on the loading screen so much as I do need to know the map I'm on.
2) I really like all the gametypes, but the playlists ensure I've never played on the same map twice in a row which would be a godsend for learning them
3) There's no way to just select and play on a specific map.
I would murder for the ability to just start a match that didn't count and run around the maps on my own or with friends. The controls are so amazing this would make for hours of fun for me in its own right, just getting to explore them at my leisure. Hmmmm sigh.
