1) a lot of that killing power comes from bacteria in their saliva which they don't have in captivity.
2) yes, they have venom, but so do all other monitors, including crocodile monitors
3) komodo dragons are fairly docile in captivity, and will even come to be petted. croc monitors, on the other hand, are incredibly difficult to tame, and even then they still have a short fuse, and could turn on you at any minute.
4) crocodile monitors are actually the longer (not heavier) i have heard of them reaching 12-13 feet.
in short, they both have deadly potential. i would much rather have the more docile one, which is also a lot heavier, and probably slower. croc monitors are climbers, and are strong and lightweight. komodo dragons are stronger, but they also weigh a lot more. if i had to guess, i'd say the croc monitor is faster.
so, if you had to pick one..
croc monitor: fast, usually very aggressive, and unpredictable.
komodo: a little slower, usually docile.
i think i know which i'd pick..
