I have my own dairy cows... Grew up with a dairy cow. In all my experience with showing people the raw-milk light, I have NEVER had a bad reaction. They are always glowing. When I was a kid, it was like a game I played when having friends over... How Much Will They Drink In One Sitting?!?! Or something of that nature. *haha* I had a good girlfriend of mine in junior high drink a gallon and a half over a one hour period while we ate dinner and made dessert.
It IS different, but absolutely in a good way. The mouth-feel is definitely different, but good like above posters mentioned. It also depends on the diet of the cow... I have my cow on a low grain, corn free diet, and her milk isn't as sweet and the cream is less filmy... Two things that I find very pleasant. I used to be a milk-hater as a kid... Even with our home-grown milk. But we had the family cow on a high-grain, corn-inclusive diet. So that makes a difference. As does the breed of cow... Jersey's being sweeter and creamier, Holsteins less so.
As far as the cream goes... The longer you let it sit the thicker and "drier" it will become. It is harder to reincorporate if it has sat untouched for over three days. In fact, if you want to make butter or drink absolutely skim milk, that is the ideal time to let it sit, so that all the cream rises and there is less milk in the cream. If you are shaking it from day one, it will stay mixed in pretty well... But be careful! If you are shaking a whole gallon a few times a day for a few days, you'll end up with butter floating on your milk. *haha*
There are a lot of things that play into the taste of raw-milk, but generally it is still milk... Not like an apples to oranges thing. You've got to be a real milk connoisseur to point out all the minute differences other than the fact that it tastes so much better.

Funny notes on consistency and quality... I've had people think they were drinking whole milk when they were drinking skim... It's that rich and good. I water extra milk down for my animals, and can dilute it way over half water before it starts to look as watery as store bought skim. Creepy!
