Go to Mods

what is your go to mod that you always install when playing minecraft modded!? mine is Project E! i always have it

It is Worldedit, it saves so much time in Creative mode.

I've got a pretty long list of mods I really enjoy, plus a list of mods that just make the job of running a server so much easier. If I had to pick just one mod, it would be a toss-up between mcMMO and ChestShop though.
