starting again... figured i was done for a while

so my son hits me up after months of not playing wow today saying he wants to play again. after explaining i lost his account and i will get him a new one i figure might as well do some research as to what realm. i looked through wiki for MB friendly realms but it seems a little sketchy for info. it says the largest alliance pve population is on Al'Akir. any other player info or links to a good post about where people are at. did the search but i think im searching the wrong things cause im not getting many relevent results. thanks for any help.
