I prefer to run legit whenever possible, even stating that in my LFG posts. That being said I'm not waiting around staring at my computer for an hour waiting for more people who think the same. Also I feel like I have a pretty good understanding of the mechanics of the fight and with that in mind I know when a group simply doesn't have what it takes to beat the encounter. In these situations I'll stay with them and finish it with cheese. Hard to find good groups for Crota CP legit as most people will just do it from the fresh run. I've also purposely cheesed when trying to run low levels through the encounter.
