Different Types of Protein
Whey Protein- Whey is a milk derived soluble protein that is quickly digested. Whey has been clinically shown to increase protein synthesis by as much as 68% when consumed post workout. This is because whey gives your body a flood of amino acids very quickly, causing a rise in protein synthesis.
So what is it good for: Whey is good when consumed post workout because your muscle's need protein fast and whey gives it to them fast, since it is digested in about 30 minutes. For this same reason, you should not take whey on an empty stomach or by itself at any other time of the day.
Another reason whey should only really be used post workout is because at any other time when it is taken by itself your body only uses about 30% of the amino acids. You see, whey gives your body such a quick flood of aminos that the body thinks it has more protein than it actually does and it sends the "excess" to the liver, where it is oxidized and used as energy.
Casein- Casein is the opposite of whey. It is an insoluble, slow-digesting, milk derived protein. Casein has been shown to be anti-catabolic in several studies but has no effect on increasing protein synthesis. So what is it good for: Casein gels in the stomach and is slow to digest.
In fact it takes casein at least 2.5 hours to digest and up to 4 in some cases. For that reason it is good at any meal other than post workout. Casein is an excellent choice especially right before bed since it gives you a slow stream of aminos over about 3-4 hours and prevents muscle breakdown. You need this slow stream of aminos since your body will be going 8 hours without any protein.
Soy- Derived from, you guessed it, soy plants! Soy is very unique because it is the only complete, non animal protein. Complete means that it contains all the essential and non-essential amino acids. Soy contains flavones, which are good for your health, and has been shown in some studies to reduce the risk of cancer.
It is also rich in Glutamine, which is perhaps the most bodybuilding important amino acid. So what's it good for? Overall, soy is good for your health, and one or two servings a day would be a good idea. However there are better proteins for bodybuilder's goals. As far as the notion that soy raises estrogen levels goes, it is true but only if you consume abnormally large amounts of soy, so don't be scared to have soy every once and awhile.
Egg Protein- Eggs have the best amino acid profile available on a single protein. They also have the highest net nitrogen utilization rating, which means that you use more nitrogen which is what actually builds the muscle. Think about it, you're eating a complete animal, it's nature's gift to bodybuilders.
I personally have experienced noticeable gains when I increased my egg consumption. Egg is a medium rate digesting protein, about 1.5-3 hours. So what is it good for: Egg protein would be good at breakfast, lunch, whenever, save post workout and before bed.

I just didn't include. Not on purpose or anything but I just left them out mindlessly. lol
Let's not get all bent out of shape you carnivores

Just curious how it compares in terms of digestion times etc...
I consider eating normal eggs to be a carnivores act, but that's just my own opinion, not a fact

Since you brought it up, why don't you find some info on animal protein and such so I can add it to the post. Respectively I will give you credit for the info
