I absolutely love my rats and currentlly have 10 different North American Rats and a pair of Japanese Rats. On the whole, they are some of the easiest and most attractive snakes in the hobby. They are ready feeders and easy to breed. This also means good quality snakes are readily available at a reasonable price. A temp gradient of about 75-85 is good and moderate humidity is generally OK. My snake room humidity is at 40% today. To me, one of the big pluses of Rats vs Corns is the climbing. The Black, Yellow, Everglades and Grey Rats also love to climb so that is a plus in a display cage. Personally, I have found Texas Rats to be a little different. There are some terrific colors available and my favorite is the Orange Pahse from Dwight Good. Although there are other folks with differing experience, I have found some to be a little snippy. On the other hand, I have been able to tame all of them that were snippy. If you find one as a juvenile that doesn't snap at you, he'll be a good adult. Just be sure it isn't simply because the snake is cold. In the words a of a great man, "This is just my opinion."
