I'm from the Midwest and yes everyone 'from Florida' will tell you you have to be way south for warm weather during their winters.
But then again they think 50 degrees is 'freezing cold' ! B
The first time I came down I stayed on my friends property. One day the temps got 'all the way down' to 60 degrees and I swear they came out of their house with winter coats on, gloves and boots! I came out with just a t-shirt on sitting in the lawn chair outside my MH enjoying the hot sun and they wanted to have me committed.
It's all relevant where you come from as to what is cold!
First 2 years I stayed in central Florida around Leesburg. This year I moved up north above the imaginary line of what Floridians call the cold zone, I.E. Ocala. It is usually 10 degrees cooler in this area less mosquitoes and I for one am going to enjoy every single minute of it.

Southwest and South Fla. are warmer in the winter period. The frost line is Tampa as the temps do vary quite a bit between Tampa and areas south. I am a former snowbird from the Midwest who spent two winters deciding on where to build. Yes the further south you go the warmer it gets but this winter the temps and I watch the weather every day only varied a couple of degrees say between Englewood and Naples. Also the weather is nicer the closer you are to the gulf. The parks are usually less expensive inland but if you come for the beaches you may have to drive. If you can use a computer you can get some nice places at the state parks for under $30.00 night. But you have to book early. Bugs are not an issue in the winter.
As far as rates go between the two:
Florida has the highest CG fees I have ever encountered.......except that is, for California!
I honestly don't see why people don't just snowbird to So Georgia. IMHO, JMHO the CG's are far nicer and the rates are way lower.
Last time down I stopped in Perry, Ga for the night and ended up staying there for well over a month. Clean, nice, and no extra charges for electric and lots of amenities for way less than what I ended up paying after I crossed the state line!
As you might have gathered from the responses, there's not significant difference between the tempature on East vs West coast of Florida - it's really a longitudinal thing; the further south you go the warmer you go.
The one thing that might make a difference in cold snaps is proximity to the ocean and I believe the West coast of Florida has more RV parks close to the water than the East Coast (being 5 miles vs 25 miles to the coast line make be the difference between staying above freezing and going below freezing during a cold period).
If you care about ocean temperature, I do believe the water along the East coast (Atlantic) is warmer than the water along the West coast (Gulf) but it's not a huge difference and again, the further south, the warmer it is.
