This is always a tough question. Most of the time players tend to be prejudiced toward---or against---their own server and unless someone has played a lot on a bunch of different servers, it's always hard to be able to compare them, especially for starting out.
Stromm was the last new server added and it has a rep of being good for noobies but I levelled 2 toons to 73 on Stromm and my experience was that it was a good thing I had mercs to help me because I really didn't notice tons of low level players. I was able to make low-level groups but that's because I'm very vocal about wanting to group. Here's a tip: you will NOT have much luck at all finding groups if all you do is type /lfg. In fact, your luck will be miserable. Far better to announce periodically in general chat you're LFG. Much better to FORM A GROUP (even if it's just you and an alt, or you and a merc) and announce in general that you've got a group LFmore!
You know how in the LFG window there's a section for Groups LFMore? You know how that page is almost always empty? It's not empty when I play if my group isn't full. I USE that window; I wish others did.
My mains are on Saryrn. It's an "average" server. But if you wanna make a new toon on it, let me know (PM me here or email to sippin@hotmail.com.) I'd be happy to help you out.
It's every player's obligation to encourage fresh blood to the game!
