T3000 and Connor wins. Better durability, more strength, and he can break himself apart to move through an opponent like he did to Arnold. Only way to beat him is with magnetic force.

Yeah, I thought that was pretty cool when each of his "layers" was beating the hell out of Arnold. But since the T1000 is virtually indestructible. Wouldn't they pretty much be fighting endlessly? (As long as they aren't in an area with extreme temperatures and no magnets are involved, of course)

T1000 is more vulnerable. Extreme heat (molten metal) volatile substances (chemicals) or pretty much anything that can melt or degrade metal can destroy it. Plus, the T1000 has to recollect any of the metal separated from its body.

True true. But that's why I asked about it occuring in an area that didn't have extreme temperatures lol. But then again it would take it a few seconds to reform itself to repair the damage. Which would be more than enough time for Connor to continue beating the shet out of it. I guess another thing that would come into play would be that it shuts down for a few seconds after taking excessive damage. Like when Reese put rounds into him while getting clothes, he just laid there for all of two seconds before reconstituting himself and starting to move again. Which would make quite a difference while fighting john. Oh well, I know its gonna be great seeing a T1000 Arny kicking ass in the next film.
