I'm partial to I-80. It's only the second longest (I-90 holds the #1 spot), and it ends 4 miles short of reaching NYC, but for diversity of scenery, it's the best. From practically the shadows of Manhattan skyscrapers it traverses the heavily wooded sparsely populated northern part of PA, through the industrial Midwest all the way to just south of Chicago, then the Midwest farm belt, the Great Plains (some argue that I-80 across Nebraska is the longest, most boring stretch of highway in the nation, though I'd give that honor to I-10 across TX), then through the Rockies, along the Great Salt Lake, through the Nevada desert, the Cascades, through California wine country and right into the heart of San Francisco.
You may have been traveling at night, but I-10 in Texas goes through rolling woodlands between Houston and San Antonio, scenic hill country northwest of San Antonio, and then in view of several mountain ranges in west Texas. However, there are long boring stretches as well, which can make one forget the nice stretches.
I-80 is the best, at least when it comes to cities. Starts in NYC metro, then goes through Cleveland, Chicago, Des Moines, Omaha, Salt Lake City, Reno, Sacramento, and ends in San Francisco.
The only problem is I-80 doesn't go directly through some of these cities. For example for Cleveland and Chicago, it goes through the south suburbs of these cities. So you won't see these cities from the interstate itself, you'll have to go a bit out of the way to see them. Still, it's hard to beat the trio of NYC, Chicago, and SF, with the variation of seeing the Northeast, Midwest, mountain west, desert southwest, and west coast.
I-70 is probably my second favorite. Baltimore, Columbus, Indianapolis, St Louis, Kansas City, Denver, and ends in Utah. And unlike I-80, I-70 does go through the heart of most of its cities, which is really cool to see every skyline along the trip, right up close. The only issue is, there is a *lot* of boring stretches in the Midwestern in between cities.
I-10 has some good cities along it (LA, Phoenix, SA, Houston, NO) but it's a bit too much the same feeling driving from Jacksonville all the way into Texas. Basically just driving through southern forests and along the Gulf Coast for a great deal of the southern portion. Then it feels all the same driving through the desert southwest from Texas all the way to east of LA. So it only feels like going through two different regions, whereas the more northern interstates go through the Appalachia/Northeastern old cities, then the rust belt Midwest, then mountain west, then some desert, then west coast. There's more variation in feel of the road trip in the northern routes IMO.
I-90 definitely wins on the sheer amount of national parks and non-city tourist attractions, and even on cities it's no slouch, with Boston, Buffalo, Cleveland, Chicago, Madison, Spokane, Seattle. It's definitely on my bucket list to some day to an I-90 road trip from coast to coast.
