I know the "old guard" tends to favor enamels and laquers, back in the day they were superior and you folks have been working with them longer than some of us have been alive, so you'll find a lot of love expressed for enamels. not without good reason though, they can look really darn nice.
I wouldn't shake my fist too hard at acrylics though, they've improved over the years for hobby use, they're convenient and more accessible for some, and I don't think it's fair to scoff and limit anyone's ability to enjoy the hobby because they use acrylics :p
I've used Testors and Tamiya spray cans. I like Tamiya's spray cans a lot, especially their primers. My experience with Testors has been good so far, but more limited.
I haven't airbrushed yet but I will be soon. I have a stock of Tamiya and Vallejo bottles, and the Badger primer to try out, so hopefully I'll have a little more opinion to offer after.
