Well, after a month or so at CF, here are my thoughts from being an ex-FF member (well not really ex-FF, just froze my membership and still have the option of joining back): -
Previous FF club: Aeon KBT
Current CF club: Aeon BIG Bkt Rimau
CF over FF:
1. Fees is cheaper. Home membership 149.
2. Equipment newer than FF.
3. Crowd is younger.
4. The water dispenser dispenses cold water. (If you've been to FF KBT you will know that the water dispenser there hasn't been dispensing cold water for ages)
5. Parking is FREE
6. RPM Studio (main reason why I jumped ship)
FF over CF:
1. Locker and Shower facilities much bigger and has better ventilation (the CF one will get smelly once a while and the cleaner will have to spray air freshner, haha)
2. The GX attendees are more hardcore - they make more noise during the class, hence give you more semangat. The CF crowd all looks like newbies and very quiet. Maybe takes time.
3. Towel is better quality
4. Water pressure at the shower is excellent. Can't say the same of CF Bkt Rimau
So I still have mix feelings about the whole thing, but I suppose the CF is pretty new so see how it goes in the coming couple of months or so

To cancel CF contract before expired need to pay RM400.00 penalty fees. Perhaps it is good for you to consider to stay in CF for at least a year. That's the rule last time, no sure if change now.
You also need to decide what you want to do with your existing FF membership that are still active.
