Crota is the safest bet, by far (Destiny)

One difference: I'd enjoy playing VoG every night for weeks. Crota, less so I think.

VoG was harder, in terms of actual difficulty, and mentally. You've go the conflux session which isn't that difficult, but is just long. It's a lot of 'waiting' where you can't really do anything to move it forward but let the timers run out. Crota has none of that.
