I was thinking top-visited, but then I realized why not just let the player's have full control over the list? For example, what if a player has worked on... we'll call it UC1, for a couple months. Bam, they quit, go working on UC2. However, because of the statistics, UC1 will still be at the top of their list for a long time because of all the time they spent on that server working. Add in a lot of servers and you could possibly not see the server you are interested at the top(and thus, not listed at all) for a while.

Not to mention gathering statistics seems like way more work.
