Hal fought Zod and Cyborg Superman. He even legitimately defeated Zod unded two yellow suns.Superman faced Sinestro before that. He looked a lot worse for it then Hal, frankly, which is a credit to the writers willingness to make an off brand villian look credible against their flagship hero.
Back Adam and the Marvel family villians have had confrontations with Superman since the Pre Crisis era. Flash Villian Hector Hammond was a thorn in Green Lanterns side, teaming up with Grodd. Kyle Rayner took out Mongul, as did Hal, as did Flash (Mongul classic became a bit of a joke)
Villian crossovers happened all the time, since all eras of DC.
Except Zod LET Hal beat him but back to the point. They don’t switch around as often and a few of the examples oh gave took place in team books
