Playing on a PvP server you *will* get ganked (i.e. killed by a group or ??) more often than you come across a "fair" fight. However, the "fair" fights can really be a lot of fun. I played for quite some time on a PvP server and it had good moments and bad. Eventually, I transferred off simply because I felt I needed to play a TON just to keep up with the gear required to even survive. I enjoyed it, but I know I'd hate it undergeared compared to the rest of the server.
I'd echo what other have said about low level bgs...stay away unless you just really enjoy them.
