Go with the T100. I looked at both when I bought mine, and I'm very happy with the T. A few people I know at work have Tundras, and though they are a good truck, they are not that good on gas. Also, you will get a better truck for the money if you buy the T. They were built in Japan, which adds to their quality. (I hate to admit that, but I work for a ***** company, and have been to Japan a few times. As a country/culture, they follow the rules.) I am 6'3", with most of my height in my legs, and I find the truck to be comfortable too. I have a 98 with buckets.
Good luck!!
