Battletoads falls into the latter. Silver Surfer in the former. Castlevania NES in the former. Super Ghosts and Ghouls would fall in the latter. Protip: If I had to restart the entire game every time I lost a few times, a lot of recent games would be ridiculously, tediously hard too.
The hardest recent game I can think of is Shiny Gold time trials on Donkey Kong Country Returns, or Mirror Mode level 6-K, Perilous Passge, same game. You will tear your hair out in painful agony for hours trying to get through that damn level. I had 99 lives and left with about 60, despite all the extra lives I got from bananas.
Alternatively, Castlevania: Order of Ecclesia on hard. Level capped at 50, or even lower if you're feeling really ballsy. (PS: All the bosses nearly one-shot you, and can take quite some time to kill. Have fun.)
