We're a raw milk household, and I found an added benefit was the lack of histamines which are apparently released during the Pasteurisation process, I now suffer dramatically less allergy attacks than I used to, and I haven't had to restock with Benadryl since we started using it. We get ours from Peak House Farm, Cole Henley, in Hampshire. Yes, you can freeze it (as long as you have the plastic bottles, not the glass ones!).
Yes, non-pasteurised doesn't last as long, but as it is so much fresher when you get it (same day, or early in the day it'll be the previous days) as compared to about a week old for pasteurised, I don't consider it to be an issue. The whole milk buying machine and surroundings are impressively clean at our place, which is more than could be said for the production dairy/bottling plant that I used to do building design and maintenance work for.
At work I use skimmed, because that is what my manager insisted on, and since she's gone, I've stuck with it, as I reckon it can't have much of the histamines in it, as it hasn't got much of anything in it! I won't have to buy any more of that, as I retire next week
