This is actually really hard to choose. I ended up liking SOA more than I thought I would after a very average first album. Their second was pretty damn good.
I also am a big Dominici fan.
I also just happen to be a huge of nostalgia.
After the WDADRU reunion with Dominici, there was talk of Dominici getting back into music. His first foray was his acoustic album which I really enjoyed. Bought an autographed copy and told him as cool as it was, I would love to hear something more DT sounding. Eventually Mike set him up with some DT fans that had a prog band from...I don't remember, Italy? Charlie's wife at the time was from, I don't know, Hungry? They moved over there so he could be closer to his band and got a record deal.
He released Part 2 and it was awesome. Nothing groundbreaking. Just cool and enjoyable.
Part 3 is actually my favorite but the bummer is, once it was released, that's when the band was effectively over. They had only played a handful of shows, most of those were opening for DT in eastern europe.
So, there needs to be a "tie" option because that's where I'm leaning. Perhaps it's not fair since part of SOA's problem was the hype and the eventual let down. Maybe I'd vote for them over Dominici if their third album is as good as the last.
Definitely two of my favorite bands of the "former DT members" but if we were having an ultimate face off, I think Chroma Key would win because I listen to those songs a lot more.
