If you want to play only with your friends, any 3.3.5 repack will be fine. You could use Novos easy repack (or smth like this, i dont know the full name).
If you want to host a public private server, then dont use a repack. Always compile the newest core by yourself to get the latest bugfixes and things like this.
If you want to do many custom things, i can recommend ArcEmu, otherwise you should use TrinityCore.
