Would you change a Triaxis for a 6505+?

I never used one, but Ensiferum's s/t rhythms were Triaxis and I think they sound great.

edit: relistening, they're okay, not that good come to think of it
 
I also love James' tone, but I think it is a bit myth about this. He manily used MkIIC and MkIV. Triaxis was only Load and Reload I think, and combined with other amps I guess.

Triaxis is great for soloing but not for rythm guitars.

i'm talking specifically about his live tone, not studio.
