only way to find out truly is to have a tournement in conn, see who's the best.
just because your well known on the forums or for taking charge in cap battles doesn't make you the best
I've noticed a lack of names for gunboats. Unless gunboats are rolled into the "caps" category?
I personally haven't a clue who's who in the PvP scene, besides Vasko, Wesker and Thunderer, and that's mainly thanks to their names being tossed around so frequently.
There is... One, that I know of from experience, both as witness, and first-hand account. Out of all the Reavers, Silver was the most deadly of the bunch, and recently came back to Disco. I would definitely count Silver.
