Troll Vs. Cave Troll

(HP) Troll (One very much like the Dungeon Troll in Harry Potter and the Sorcerer's Stone) VS. (LOTR) The Cave Troll in any of the LOTR movies.
I was watching FOTR last night and began thinking about it during the scene of Balin's Tomb and thought I should create a thread, getting opinions and so forth since this Forum is beyond dead.

How about a Mountain Troll instead. A Mountain Troll is a lot bigger then a Cave Troll and stronger plus Mordor uses them over Cave Trolls.

Cave Troll = Don't really know.
Mountain Troll = Mountain Troll wins

The Olog Hai trolls would deffinatly beat any HP troll!

yup
