Definitely both.
On the fantasy side: North Point, Chatham, Sardian Park from Sports Car GT (yeah, quite an old one, but lot of memories), Grand Valley, Trial Mountain, Autumn Ring from Gran Turismo, La Dehesa, Reservoir GP, Hills of Death from rFactor 1, Fonteny, Gentrack from Assetto Corsa and many more.
Real life favorites are quite standard, Nürburgring-Norschleife, Circuit de la Sarthe, Spa-Francorchamps, Monza, Suzuka, Fuji, Zhejiang, Sebring, Daytone, Kyalami etc.
