In a proper role-playing environment, I really enjoy Gangrels because unlike most clans, you are allowed to be unique. Most clans carry stereotypes and clan politics, while Gangrels are loners and survivors. They are taleswappers and travellers, but your clanmates aren't looking over your shoulder telling you what to do.
The WoD is an oppressive setting, and the Camarilla is a dangerous place of political intrigue. Gangrels are given a wide berth, and they are quite combat capable to boot.
