I know you are not doing SAW runs, but thought you might like to see some back to back comparisons from my Mono hull boat.
All I did was swap LiPos and cool down the motor between runs. These are 3s/6s setups but they offer the same brands in 4s.
- GensAce is very similar to Zeee as a cheap option. (you get what you pay for)
- CNHL G+ 70c is the highest output lipo from CNHL (ignore what they say about c-ratings)
CNHL is budget friendly and if not being pushed to 400+ amps would probably be a great option for most people.
- ONYX is top tier right on par with SMC from all the data I have seen.
