The issue with FTP or BTP is the niche is small and the pie has been saturated with butter but its not getting any bigger. Pay 2 play with plex is my vote.
I prefer a P2P system mostly due to it requiring players to have some investment in the game--thereby allowing some kind of limitation on behaviors. There will be those who will cry from F2P and announce the doom and gloom of not going that way, but my experience is that F2P games have an inordinate amount of people behaving badly strictly to be be people behaving badly.
The only issue will be that many will automatically say that P2P is also P2W....which I think is a twist on the F2P argument.
I like the EVE structure, and I like their economy model, so that kind of gives you an idea of where I am coming from.
