I think the outcome varies on a huge amount of variables:
-equipment
-how they've used their SP
-distribution of STR & INT
etc etc
I've seen some badass nukers go down in seconds when some full str fire glavie user comes in with a glavie that has some insane criticals and using combos!
Mainly though it is up to the few first hits and how they are handled. If the tanker who just got nuked doesn't have the wits and speed to quickly attack back, heal himself like crazy AND prepare all his combos and all, he might take the loss. But if he does get all this done, I would say that the nuker will be served as dinner later that night.
Depends a lot on peoples style of play. Personally, I've always disliked this type of conversations in the sense that it usually degrades to a yes/no argument:D
Anyways, it's really much up to how both people play, what they are armed with, what they are using for protection, etc
