I found an old post that had this question already asked. It seems like both work well, the biggest difference is Flexwatt require more setup and are usually better for racks, and Ultratherms are out-of-the-box ready UTH's that work better for a single tank. So I think I'm gunna go for the Ultratherm then, even though it's a bit more expensive.
