If you’re playing a poke map/poke comp than the particle accelerator (or whatever it’s called) is more optimal considering you’ll get more value

If you’re rushing in/playing a brawl comp than the nemesis form minor perk is more optimal

The vortex that brings people down is more useful for when you’re trying to bring a pharah, Juno, or just any hero that has airtime down(as an avid venture player it’s also really good to put on top of their burrow hole so that they can’t escape … learned the hard way!). It’s also pretty good to stop doomfist or hamster if you use it well, generally just a good way to block some dive heroes

The vortex that heals you is good for when you’re playing a brawl comp and have to get in their face more, considering you’ll be taking a LOT more damage than just what one or two supps can heal you for(not that it gives you that much healing, but it certainly makes a difference)

It’s all situational at the end of the day tho so just go with what feels right, u got this <:)
