I've done a lot of tube rolling in various amps.The smaller signal,phase inverters etc.,seem to have some changes in transparency,less distortion,and some sonic characteristics.Changing the outputs had the most change in the amps sound characteristics.I can't speak for your amp,but in general the Chinese and JJ made outputs will be brighter and more detailed.The SED brand will have sort of a lush,and more liquidy characteristic.Its been to long to say what the KT88/6550 most modern tubes will sound like.In general what I'm trying to say is,the outputs will give you the most different sound between brands.For a different sound,maybe try the outputs first.
how much tubes influence on the sound ???
