They're about the same thickness and number of pages and I've read them at about the same age. Timescape got the Nebula award, Red Mars got the BSFA and Nebula awards. They have about the same number of stars on Goodreads, so roughly the same reception? I haven't finished reading Red Mars, I think I grew tired with the endless descriptions. Maybe the other two Mars books are better? Dunno, never got around reading them, moved on. Both might be okay books to turn into movies, with Red Mars just use the lenghty descriptions as documentation for filming the scenes.
