Best Watch face?

I know what I am asking is very subjective/personel, but I am just wondering what watch face people use. I am still trying to find a suitable watch face.

I saw a co-worker wearing a fenix 7x and he had a nice watch face (MARQ Adventurer MB). Now I am wondering; what else cool watch faces are there? Also, does it drain the battery?

Right now I have tried:

- Data Lover
- ASAP

I use the latter right now due to the fact that I don't know if Data Lover drains the battery or not.
What do you use?
