My take -- purely personal . . .
Aintree -- Very fast and flowing. Wonderful if dry, but only three corners, lots of need for power, lots of grip, but a tendency to pour with rain in the middle of a class
Three Sisters -- A kart track. Lots of video available. IMHO uninteresting, but many people love it.
MIRA -- You know. Very grippy. Quite technical. Generally fun (if "only" four corners -- the fifth is actually a straight!).
Hethel -- Very fast, but not flowing. The ultimate power circuit with a bit of technical thrown in. Always friendly and comparatively well organised (B19), Deepest Norfolk, but I'll probably be there.
Brands Hatch -- The most exhilarating circuit in the country, basta! Very fast and flowing. Paddock Bend intimidating but gorgeous. Only a morning, but more track time than many full sprint days at the likes of Curborough or MIRA, just compressed into shorter elapsed time. Difficult if you have car problems (little time to rectify). Undeniably expensive, but you can afford it. The one meeting in the year that I'll rearrange holidays to attend. Chris' video at
I suppose my recommendation is clear
All best
