Triode or Ultralinear

I have a Primaluna integrated amp that can be switched to either mode. When I first got the amp I thought Triode was the only way to go. It sounded a lot different than my SS Mac amp which I thought was the tube sound everyone was after. To be honest I really liked the sound. After a year now I recently tried to listen to the amp in Ultralinear to compare. It took a week or so but now I think the ultralinear in better. It sounds a lot less "tubeish" i guess, but the sound is much more full (which was one of my problems). What are peoples opinion on this? Is this just a case of liking something different?
