any decent amp with the appropriate speaker will always work to the design goal you wanted to accomplish. Of course, the number one challenge is : what speaker would that be?
a good sounding setup will always be good sounding, - with different genre of materials? This is just ideal, paper concept. There is just no cure-all set-up.
What's best, therefore, is something you have to define yourself. If a 50-50 is best for you, or a 2 set-ups each working 100% perfectly for you for every selected genre.
At the end of the day, it is all just personal preferences. Not all guitarists prefer tube amps! And all of us, vary in some degree, how we want to hear things from our set-up.
How about a set-up that you can vary any time of day, depending on your mood and depending on your genre to play?
