In my opinion Malden it's almost a perfect "life map".
First of all it has nice landscapes. It looks cool and natural. It has a little bit of everything, excepting the fact that it's a medium-sized map. Second, it has great housing. I think this will be one of the best maps for roleplay after Altis, of course.
Tanoa isn't for everyone. It has a lot of lag and useless foliage, even if it has great towns wich are perfect for roleplay.
Stratis it's to small and without structures, houses, or cityes. Imo Stratis it's not a map for roleplay, it's for Wasteland, KOTH, and lots of fire
