I can simplify it!
Basically, there's no reason to choose any amp in that list over the Mesa. None of them do anything better than the Mesa. Every amp listed there is a good starter amp that you will later upgrade to something at the level of the Mesa, so why not just get the Mesa and be done?
I want to agree with this because I do love the Mesa a lot for what it is but if you're looking for a more modern accentuated mid kinda sound the GK and Traynors do it...well I won't say better but maybe more naturally.
