Type-specific banners are only good if you need support units for a specific team, and you might not even get that particular support unit that you need. Plus, these banners always come back. On the other hand, Super 17's banner features two 120% leaders (Super 17 and SSJ4 Vegeta) and also Super Vegito and Rosé, and dupes are always nice, unless you already have too many of them. You definitely want SSJ4 Vegeta, both as a leader and as a unit on PHY Omega's team (for when his leader skill gets released), but you might get Super Vegito and Rosé dupes instead, so it's up to you to decide if it's worth the risk. And I'm sure SSJ4 Vegeta will also come back in a few months.

By the way, look out for STR Janemba & INT Gogeta's dual dokkan festival banners in November, which will feature amazing units and also a discount on multi-summons (1st multi - 25 stones, 2nd multi - 30 stones, 3rd multi - 50 stones, 4th multi - free).
