In my opinion, Leaders tend to suffer in growth, that is if they work as hard as they should be doing internally, especially at this stage. They tend to have less time to sort out their own account, generally a good leader can end up being an average player, it's learning how to manage time correctly.
But it does depend on circumstances and at this stage, it is hard to tell who will stand and who will fall, but after all, isn't that part of the fun?
I believe Virtus is a good tribe, Leader seems to be down to earth with good values.
I also know a couple of their players and know from experience they are definitely one to watch...
But hell, how could I say anything bad after his last post ^.^
