Greek yogurt (nonfat) is both the cheaper protein ($0.035/g against $0.055/g) and the leaner one (16.9 g protein per 100 kcal against 11.4 g). Most matchups force you to pick a side.

One of these is a convenience purchase

Ground beef 90/10 (raw) ranks #23 of 25 on cost per gram of protein, near the bottom.

If it is there because it travels well or you enjoy it, that is a different and perfectly good reason.
