I'll put the DPS results with the Durin team and all the builds in the comments. The rot with Durin is a bit more straightforward, since you don't need to swap back to Durin for the pyro infusion on Venti's burst, but other than that the rot is pretty much the same

The rot I try to keep to with this team is this

Faruzan Q + E > Bennett Q > Nicole E, Q > Venti E, Q > Bennett E > Venti N5, dash, N5, E, N5

While the rot I try to keep to with the Durin team is this

Durin E, Q, E > Faruzan Q + E, Nicole E, Q > Venti E, Q, N5, dash, N5, E, N6

There are some variances in how I perform them, cuz I haven't exactly mastered it yet. With Faruzan I say Q + E instead of Q, E cuz I use burst first if it's available, but if it's not I skill first. Wether you skill or bust first doesn't really make much of a difference afaik, so just do whichever is more optimal for smoother rots

Sadly I can't test Durin without Nicole, since I don't have the new set for Durin yet, but overall I'd say Nicole is more valuable than Durin. I'm sure Durin without Nicole ends up dealing a bit more damage in a dummy stage, but in actual combat Nicole's shield is going to be invaluable. Nicole basically means you can do your proper combos without needing to worry about dodging enemy attacks or without getting knocked around, which Venti is very prone to as a bow user. This also means you can more easily stay within Bennett's circle, since in my experience enemies tend to knock Venti outside of it a lot, which is very annoying
