It could go either way, depending on how either methods is implemented. Both have their advantages, and disadvantages.
I am more of the strong type, and not so much multifaceted. I stick to the top four functions I know best, Ni, Si, Fe, and Te. Deviating from these is hard for me. The advantage these give me is I have a strong grasp on all of them, and can use them in most any way (in particular, Ni, which I have a very very strong hold on). All four of these put together makes for all judging sets, and as such I am an extremely strong judger. It makes me firm, direct, planned, ordered, keeps me out of trouble, and lets me "know" what is coming up. The disadvantage of this is that should I need to use any of the other four functions in heavy use, I become "lost" and unconfortable, I don't know how to use them well, nor do I really want to.
The flip side of this is not nesscarrly being strong in one function, or a set of them, but having a decent grasp on nearly all of them. This allows one to bounce between all of them and navigate any situation. However, it is extremely rare for someone to be adept in all functions, so "mistakes" are often made as each function is not developed to the point where they are completely reliable. It also makes it hard for this person to truly know themselves, as they are in a way all over the place.
