It's kinda strange though... there's almost no focus; it's gonna be very hard to make any comparisons beyond whether you enjoy it or not, which is completely biased when it's relative to an individuals game mode tastes. In the last contest we had hardly any voters... is that really not going to be an issue? Especially when we're splitting up the maps into 2 categories.
Gpit and TC almost always have to have the same layout in order to work optimumly, and A/D is by far more popular than 5CP.
A/D is easily the safest choice for popularity and unique layout oppotunities, whilst 5CP is the safest choice in terms of work load (copy/paste/rotate). I'd only choose TC if i felt like i wanted to get the attention of Valve, since there's only 1 official TC map i'd imagine there's a greater chance of a community TC map going official.
