I pay for the VIP FF service(even though I'm not using it right now--but don't tell my husband that!!!!)....and I have a free subscription to FC.
I prefer FF just because that's how I learned to chart. Everything else seems confusing to me, but I haven't really tried anything else, like TCOYF. I have looked at their chart galleries on occasion, though.
Who knows, maybe someday I'll switch, but I like FF, and for the most part, I trust it!
