Well, there isn't really one specific reason that would apply differently to you specifically.
The thing is, whey is usually recommended for a different reason altogether.
See, "whey" just refers to where the protein comes from—you've also got egg-milk blends, straight dairy (like casein, though that's not always super easy to find on its own), all sorts of mixed formulas with different ratios, etc. Basically, whey is just whey protein.
Most athletes stick to whey because it digests incredibly fast. That's why people usually chug it right after a workout (often paired with some glucose). It’s probably the fastest way to get exactly what your body needs at that exact moment. In those moments, you really want something that hits your system quickly.
During the rest of the day, it doesn't really matter much (assuming you're eating a decent diet), but right after training, whey is definitely a better call than those milk-egg proteins. So, that's really why people say it's the "best." I guess "most convenient" might actually be a better way to put it.
