People keep talking about constantly having to flip between the big and small chainring on a 2x, but I doubt those people are using a modern 2x12 or if they are then they are not making full use of the cassette.
I actually ride 3X to reduce my overall shifting. Not as much of an issue if you're not using shimano STIs with the dreaded long throw of the brake lever shift, or electronic. Still have to hold/push that button. But to answer your question, no. I'd much rather shift the FD once or twice and the RD 2-3 times than shift the FD once and the RD 7+ only to have to do it again in reverse down the road 500 yards. Not much of an issue if the terrain stays constant for a while. But if it's varying constantly like a roller coaster, I'll even take friction.
