Hi, I can't contribute to the science, but I have gigged a 2 x 8 vertically aligned, lightweight cab and it was very good.
TC Electronic 208 to be precise. When paired with a 1 X 10 it was very, very capable.
Having said all that, your sound is what you like, and might not be what any of us like.
If I was to recommend a manufacturer it would be the same as @chris_b - Barefaced. Happy to guarantee you won't regret it.
