I will add some BL2 DLC input for those deciding.
I enjoyed all the DLC stories (haven't played the newest one yet). In terms of gameplay time scarletts is the longest followed by torgue and then hammerlock.
In addition to time each one has achievements on it's own. Also, each offers Raid style bosses which are great for drops. Scarletts has 2 raid bosses though 1 is rarely fought because hes a gimmicky fight. Scarlett also has (had?) a helpful bug which allows you to trick the game into thinking there are 4 players in the game. This is helpful in increasing drop rates and challenge factor. This could have been fixed in updates recently though. It also has an exploitable treasure room which can be farmed easily (again, unless it was fixed recently).
Torgue has 1 raid boss who is probably the easiest to solo, has mad drop rates, and is worth the purchase for farming purposes. In addition, the torgue DLC has torgue vending machines with guaranteed orange (rarest) rarity items in them. It makes finding those orange torgue guns much easier!
Hammerlock's is the most different of the DLCs with more unique enemies than the other 2 and also comes with a raid boss ass well.
In terms of gameplay I would recommend scarlett, torgue, then hammerlock. In terms of additional end game content for farming purposes I would put torgue on the same level as scarletts and hammerlock right after.
I found all 3 DLC stories to be fun and really funny though hammerlock gets knocked a lot, I think it has one of the funniest bosses in the game and torgue is hilarious just because of the torgue character.
