This isn't close. Cheddar Cheese packs 24.9g of protein per 100g against Skyr (Icelandic yogurt)'s 11.0g — a 13.9g gap driven mostly by how concentrated or diluted each food naturally is.

Neither has a meaningful edge on protein quality; they're close enough on amino acid profile that it isn't a differentiator here.

Cost is roughly comparable between the two ($$), so budget isn't the deciding factor here.

Cheddar Cheese's typical serving also delivers more leucine (2400mg vs Skyr (Icelandic yogurt)'s 1050mg) — relevant if the goal is maximizing the muscle-protein-synthesis trigger per meal, not just total grams.
