I probably wouldn't go far to say I preferred the second Elm Street to the original but....oh who am I kidding, of course I would.
The original is about fifteen pretty great minutes padded with a lot of lifeless horror bait padding. The second doesn't have any great moments, but is consistently fulfilling trash.
3 is where it's at though. And then 4 if you are willing to accept it pulling the franchise towards the kinds of 80s excess that made the later Rocky movies so ridiculous but so fascinating in a time capsule kinda way.
