I've found you can't make a blanket statement as to which tube is best. Every amp likes different tubes. I roll tubes in every amp I get to figure out what works best.[/quote said:

Ive gotten mixed results with the same tubes in different modded Marshalls, Its worth a bit of time to nail 'em down for a particular mod. Friedmans are voiced darker than Fortins. Langners are more compressed than most mods, and are slamming V1 hard enough to induce oscillation past 3 o clock (or 130 depending on your pickups) It all ends up being a factor in your selection of what sounds best in a particular amp. Ive also gotten good and less good versions of almost everything out there, so the particular tube thats in your hand ends up being your reference point for that brand
