I can assure you that the HobbyWing XeRun V2.1 120A / 1S 120A units are fantastic!
I've not run them for long but they are very smooth, easily tunable and seem at least as efficient as anything else out there.
Normally poor run times are due to gearing issues.
If you go for the HobbyWing ESCs I will do my best to help you out where I can.
