I'd argue that what makes those shows better is because they're taped. The actors can behave more naturally while on SNL they're standing around reading from the cue cards.
Yes, I get that the show is constantly rewritten up to the day of and that Lorne is very adamantly anti-improvising, but outside of the novelty of doing a sketch of something that happened literally that day, a lot of the live SNL skits come across very awkward and stilted.
None of you nikkas keeping that same energy for The Simpsons tho.
