Finished my second playthrough. Was level 30 this time around, tried to recruit all alies (I had two Doctor Henrys. One in an Enclave suit, one in his normal outfit), went NCR, and got more favorable outcomes for all the slides I could think of. The Alien Blaster is cheating.
This is probably the best ending for Veronica. And the Cass ending was... interesting. I want to see what Lily's is like without medication.
