Sasuke for 3v3, Darui for !v1, generally speaking.

You rarely ever need to paralysis more than 7 in 1v1, only a few teams use that many clone/summons.

Manual barrier is also much more reliable in 3v3. I would suggest a mix of auto and manual between the 3 teams thou (unless it's GNW and you KNOW your teams will be faster, than 3 of the same auto might be the best for 3x the extra effects)
