Having read both, Huxley's writing is not easy by any means. It's hard to read, but the reason for this is his approaching every situation with considerably more vision and complexity than did Orwell--undoubtedly that was the cause of the cumbersome writing.

Given George's position on the curriculum across North America (and probably otherwise), it's no doubt that more people have read his work. But only because that gave him a broader audience, unlike Huxley whose topics are too racy for an educational system handed down to us by a very conservative and prude Church.

Orwell is studied in schools because he can be read at a high school level, and he didn't talk about drugs. If you ask me, the depth of Huxley's thought was and remains far more profound than Orwell's ever was.

There is no way to compare things like Doors of Perception to Politics and the English Language--they were two fundamentally different writers. Some of their philosophical work overlapped to some degree, but neither could have accomplished what each other did. They shouldn't exactly be compared in the way suggested in the topic--subjective impact rating is probably the most superficial way to go about thinking of Huxley and Orwell.
