SSJ4 Vegeta also has a very high defense, plus he has a chance to dodge and counter super attacks, in case you want to use him as Friend (Super 17 would have less Ki though, but you could still use him to defend).

Bardock and Jackie Chun are sealers, but without Ki from the Leader skills they're going to have a hard time super attacking, and therefore sealing. So they would just end up holding your team back.
