Aero jersey or skinsuit

They were talking about this but with reference to XCO racing.

Skin suit vs bibs and Jersey

Besides the obvious of a couple watts of aero, is there any huge advantages of a skinsuit to bibs and Jersey for xco racing? What do you guys prefer? The main reason I’m asking is im a huge fan of pactimo, and I notice you can get a skinsuit from them starting at $160, versus $120+ for a bib, plus $120+ for a jersey. They also let you choose whether you want a left, a right, or no rear pocket on the skinsuit.
