I know you specifically asked about those 2 airfields ... but you might also want to consider North Weald...
I fly out of North Weald as part of an equity group in an arrow, but there is a good, active club on the airfield...
North Weald Flying Group
The North Weald Flying Group has three c172s, a c150 and a Piper Archer II which are all well maintained and in good condition.
Fuel at North Weald is very competitively priced (last I checked, cheapest in Essex), which keeps the club hire prices down.
If you want to get involved in Fly-ins and Fly-outs these are run on a reasonably regular basis.
The atmosphere at The Squadron on the airfied is warm and friendly and has a good cafe (always a plus!).
The airfield is quite active with a variety of aircraft based there so you will often find yourself in the circuit with all sorts of aircraft from a Hurricane, Spitfire, Mustang to Jet Provosts and Gnats.
As 4Screwaircrew said.. best thing to do is visit a few airfields and see which one you warm to....
