Of those two, I also choose the Mesa. Outside of those, there are some cool Laney's out there, and the old Peavey Prowler romps after a tube/ speaker change.
I've never been comfortable with the way Mesa/Boogies are voiced. I've owned a couple, including the Mark I. Just not what I want to hear I guess. I like them when others play through them though.
I'll always be a vintage Fender and Marshall man I guess...
I looked at the DC range when they came out, and found the overdrive to be cludgy. they seemed to share a common mark-era mesa trait: too much compression and an abundance of ill-defined midrange (unless you scoop them, and then you disappear in the mix).
I prefer the dsl marshalls over the tsl models. Good amps, though.
