I've seen Tskitishvili in summer league too. He's quicker on his feet than Lampe is, and he create his own shot off the dribble to some degree. He is a wing player, after all. Lampe needs to be open to shoot and doesn't shoot on the move. Comparing them isn't very informative, because Tskitishvili really is a SF and Lampe is a PF/C.
I think that Tskitishvili is closer to Cabarakapa in terms of how he plays than he is to Lampe. I haven't seen Cabarkapa in a while, so I don't know who looks better right now. Tskitishvili seems more comfortable in what he does than Lampe does, but their games are pretty dissimilar.
