Oh no, I have a full collection. Bandit 4 eva. 
Everyone seems to have them, but nobody ever used them lol. Then I pull one out for mobbing and shortly after get called a noob followed by people quittingā¦
Well, that happened once anyway, full lobby poured out after I pulled out the BS (LOL)
Heh, yes, Iāll admit I havenāt actually brought my bandit allegiances into coop⦠it might cause a revolt. 
I tried a Bandit allegiance build once, it may have been the worst thing possible, but I do enjoy some Bandit weapons. They have a bad rap, bandits aint all that bad though, thereās Krieg right?
I have two Bandits - Krieg and Maya (just started a Gaige too). Krieg works very well with them, but Maya? My bandit Maya has been some of the funnest gameplay Iāve ever had with him. It requires a completely different build to my usual approach but sheās really great at it.
There are some quality Bandit weapons even though, as you say, they donāt get much respect. RokSalt, Sledgeās Shotgun, Fuster Cluck, Slagga⦠all awesome. In terms of SMGs, the Tattler is pretty good (at least I think so!).
I donāt know whether to get all PC about this.
In all serialness, I love the Tattler on Maya, when I run a Cat for mobbing I run the Tattler and because Iām a master of portmanteaus I call it the āCattlerā build. Sledgeās Shotgun though? Thatās one I simply can not agree on, the BL1 variant was brilliant but the BL2 one kinda sucks 
all PC? 
Never mind that, itās late here (or early, thatās subjective) and Iām probably delusional.
Back on topic, I also like me a corrosive Bitch because I like blowing the limbs off Loaders then T-bagging them as they grovel or punching them as they charge up their silly eye laser.
Iām surprised to see only one mention of the Baby Maker. Itās not exactly a fave but it sure has its place.
Hellfire.
ALERT, KRIEG PLAYER SPOTTED
Well for me I love the Bitch. You have a chance of elemental spawns.
It has always been a hard drop for me to get bUT when I do get it. It is time well spent.
I still like the Hellfire myself but I might be partial from loving it in the original. The Tediore baby maker isnāt bad but can burn through ammo quickly.
I do agree regarding the sandhawk but for me personally soloing raid bosses gives it a spot in my inventory.
Just my thoughts.
My favorite is the proactive bitch with hyperion grip and sight and dahl stock. So awesome! I also really like the slagga. Most people think of it as a utility weapon and dont think its that great, but if it came in different elements
it would trump the tattler in everything but damage(including projectile speed). Its one of my favorite weapons.
In bl tps itd have to be the fast talker. You take the parts you get as this is a hard weapon to obtain, but bandit grip, hyperion or maliwan sight and dahl stock, would be ideal. 16.7 fire rate and a reload speed of under two seconds muhaha! Also the torrent is amazing! Its everything the emperor from bl2 should have been lol.
No love for the actualiser?
Ive been using a fire one and its pretty decent.
Other than that , plasma casters all the way.
I have a lower level (40) Plasma Caster and a couple of Sandhawks/Seraph SMGās I use with my Maya build if you would like to meet up and trade?
Tediore plasma caters all the way man
