IMHO, the movie wasn't that bad; it was pretty much what I expected it to be. Lots of action and two great looking gals. Remakes very rarely surpass originals, anyway...for me, this one was still fun.
As far as Jessica vs Kate clash, here's how it goes:
After successfully blocking a few attempts by Jessica, Kate traps her overconfident opponent in a very tight triangle. It is nighty nite time for Jessica.
Kate by triangle choke KO...that's how I would love to see it end
