What is the difference between (verb)こと and (verb)の?

[TheCodingFox]

I see sentences like 映画を見るのが好きです but in other sentences, the way to nominalize verbs is with こと, as in 趣味は映画を見ることです.
When do you use one or the other?

[morteASD]

Off the top of my head こと and の can most of the time be freely swapped without losing the meaning, but there are some cases where の cannot replace こと (and vice versa). Like in your second example only こと is correct, as の can’t be used at the end of the sentence with だ/です.

Maybe someone else can enlighten if there are some subtle nuances in cases where both can be used.

EDIT: Found a site explaining some of the exceptions: https://www.wasabi-jpn.com/japanese-grammar/nominalizers-koto-and-no/

To add, here’s a pretty detailed stack exchange on こと vs の.
