What's your favorite modpack?

I personally love all the mod pack with quests based using ftb quests or hardcore quest mods.
It's just awesome to play with your friends and complete all the quests, playing without quests can just become annoying after some times.

The best modpack is always modpack made by you. I hate being overcrowded with mods and items that I really dont understand. For me minecraft still is survival game so I want to boost that experience instead of being able to slay everything after day 1
