Honestly I wouldn't use the having won an award as a criteria for keeping any of them, that would be like keeping 1980 technology in 2014 because it was an award winner in it's time.
If I had to choose only one of the three it would be very difficult because CB is as close to an ADV as I have, but I think I would have to choose Frenilla in that circumstance. Of course The Virus has to stay even though since the change I actually could live without it, I rarely vape it anymore.
For me I think Wakonda will probably replace it.
As for CB maybe the Strawberry Custard will be it's replacement????
Like I said before no straight fruit vape will make my personal cut, I like Gravity but it's a one or two hit thing for me and not very often, I never tried BG or Hummingbird for those reasons.
PBC is one I probably won't try , I like Raz cup but there is no contest IHMO between it and CB, or BP, or BSP, Wakonda, Frenilla, and down the line.
Now, here's the quandary - despite not having won an award, I personally think Frenilla is better than CLS and CB both. We could just keep Frenilla and ditch both CLS and CB (to make room for PBC, Raz Cup). *waiting for the panic* LMAO
Just my 2c - taste is subjective.
