That's a really complicated question and at 4:15am I don't have the energy to answer it right now. There are a million variables in play. However, all I'll say for now is certain amps have a voicing that is more friendly to the typical recording studio environment than others.
The reason 80% of great sounding metal records use a Peavey 5150 isn't because it's that great of an amp, it's just that he way its voiced is extremely flattering through 'industry standard' studio gear/cabinets. Also, its linear midrange characteristic tends to yield good results with quad-tracking heavy guitars. Another amp may kick its ass in real life or in a live band mix, but in the hands of someone like Andy Sneap or Collin Richardson magical things can happen.
That said there are plenty of pros who record with VHTs or other amps and get killer results. Guys like James Murphy come to mind. Just keep in mind the vast majority of studios use (out of necessity) the old standards like Marshall and Mesa cabs loaded with V30s and/or GT75s. Most of them don't have cabs flattering to unique sounding amps like VHTs or Diezels floating around the studio.
