WoW Server Information

As you guys already know I am playing on a low populated server call Gideons Lair. I went to do more research on private servers and I came out with a few websites.

These websites have lists of the most popular WoW servers. Please view them and tell me what kind of server you prefer.

Priority in choosing a Server:
a) High or Low Populated ? (Low as in less than 20 or just simply don't care how many online.)
b) Lots of stuff working ?
c) High Exp Rates(40 times) or Medium(10 times) or abit (2.5 times) ?
d) Play in a server where I already have high level characters ?

So what kind of servers do you guys want? Please tag on your priorities, a, b,c ,d, in order from the highest to the lowest priority. Thank you.
