I like Veronica becuase she ponches things. I gave her Pushy and now she's REALLY tearing things up! She can die easily vs Cazzadores however. She looks good in Reinforced Leather becuase it matches up with her huge fist and hood.
I had ED-E but the sensors annoy me because it takes away the surprise factor, and I'd rather have to scan the wasteland with my binoculars to ensure safety.
In my opinion followers make the game too easy while they are alive, and if they die I feel soooo strongly that I shoudl just reload the last save file since usually they die due to stupid reasons that do not even make sense.
I haven't even found Cass and I feel she's my favorite lol. I like Veronica though, she's funny and a carpetmuncher so we get along. I let her wait at my little camp though, or at my suite in Novak.
