I had Jason as a UW teacher my first semester at Columbia. It was his first class, and he was great. I loved him. (and he's so adorable!) He made UW my favorite class even thought I wasn't too crazy about writing. Many say that UW doesn't help you become a better writer, but I think that's dependent on your teacher and what you want to get out of the class. Jason really knows about writing and is great about extracting meaning and analyzing texts... If you listen to him, and following his suggestions (espically the corrections he makes on your drafts), you really can become a better writer... Also, he's not a very difficult grader. In UW you get to write drafts for everything so if you make the corrections your TA asks you too, you really don't have a reason not to do well.
