I have not been on I-20 for years, but I have been on I-40 at the recommendations of others. It has been stated that the I-40 is a much better ride than the I-20. Just looking at the map I think I-40 is more scenic then I-20.
And Yup! Texas IS big, but not as long to cross on I-40 as it just hits the Panhandle. Plan on at least two days or more to cross her using I-20 or I-10.

It is what it is, and then it is what you make of it.
