I think the kensai is more effective as a party member. The thing to remember is the kensai is a very specific role: to deal damage. Kensai(s?) are pretty one-dimensional in nature, which is why so often they are dual-classed to improve their combat flexibility. Berserkers are a better solo class, because of their ability to tank/absorb damage and resist status effects. A kensai should be used less as a main tank, and more as a sniper, causing huge damage while staying out of the line of fire.
