I think Zwiss's Algarve (zw_algarve) is pretty good. I believe the source was Grid Autosport, which of course won't have exact mesh precision, but it has the "big feel" it needs and the way the FFB ramps up in the undulating S2 is very cool. I generally drive the RSS 90's Prototypes there.
The AI is very slow and accident-prone, perhaps to little surprise. But it is still a good time to drive. I think only an AI update (perhaps by yours truly if I ever get around to actually learning Parri's method past reading the post) is pressingly needed.
Not the case with Jerez and a few other circuits (Bahrain, Eastern Creek/Sydney MP, Yas Marina [CHQ purgatory] & Sepang being the others that immediately come to mind). If real-life onboards and the AMS2 laser scan are to be believed, this Jerez is simply not good enough.
Bahrain in particular apparently has an excellent RF2 laser scanned version.
I did note, though, that there are not a lot of stinkers that stick out in my >1200 track library. A testament to the breadth of AC modding.
I have not tried Neil Shaw's Motorland Aragon yet. I've heard it's all right.
