That would be 'omoshiroi' winning by a landslide. And unlike the other two, you only have a single 'i' at the end of 'omoshiroi'. You have the translation 'interesting' for 'omoshiroi', which is not wrong. But we use the word to mean 'funny' much more often.

Sometimes you will hear 'okashii' from someone watching a stand-up comedy, but not nearly as often as 'omoshiroi'.

'Tanoshii' would be out of the question in this case.
