I always enjoyed Lost Highway for its visceral tone and dark, almost operatic movements, but it always came across to me as much less of a complex puzzle box, ala Mulholland Drive, and more so a direct plunge into psychosis, as the viewer is placed smack dab in the middle of the main character's psychotic break, resulting in a communal psychogenic fugue. Both films have nightmarish sequences, with perhaps Mulholland Drive Being more on-the-nose in its presentation as a fever dream.
As far as the reactions of others are concerned, I have sat down with many different people to watch Lynch films, and I have found that Lost Highway was clearly the more impenetrable of the two as far as the other viewers were concerned. These people ranged from other fans of dark/surreal film, to normie viewers who have never seen anything even remotely akin to a Lynch picture. On the whole, no matter what their cinematic background, people seemed to have a bit easier time parsing Mulholland Drive. There is a certain elegance to Mulholland Drive, and once a few scenes click, it all sort of falls into place, with of course some of Lynch's room to dream still present. Lost Highway, on the other hand, tends to be stubbornly obtuse and cryptic no matter the angle of analytical approach - perhaps it really is the more dream-like after all.
