I am quite happy with the Gallente Assault frigates. I've happily engaged in solo PVP with an Enyo and taken down cruisers.
T2 frigate gangs can be tremendous fun too. You've got a lot of mobility and a surprising amount of DPS 9huge chunks of which come from the Assault Frigates!).
I would not object to a fourth bonus though! However I do not view the ship class as broken and in dire need of it (by the way I PVP in factional warfare).
