As overall universities, UT and Washington are pretty similar peer schools. I think UT has a slight edge, but nothing huge. They're both top 10 public universities, and I think you'll be happy at either one.
For journalism/linguistics, I again think UT has a slight edge, but there's not going to be a huge difference.
INTERNSHIP OPPORTUNITIES: Seattle seems to be a tiny bit better? More media.
Texas is a much more populous state than WA. There will likely be more media opportunities in Dallas/Houston than Seattle.
