The best way, meaning shortest, is via I-15 up through LV and St. George UT, Pick up the 70 to Denver, 76 to Ft. Morgan, then I-80 into Iowa. No tolls and shorter than going through Kansas, and it's interstate all the way.
You will, on I-70, have to go through the Eisenhower/Johnson tunnel west of Denver. No big deal, but some people do not like tunnels.
There is no issue for gas along any of the possible routes, really, and it depends more on what type of scenery you prefer and when during the year you intend to travel. If you are going during snow season, you might want to stay south longer. I have done that several times over the years not wanting to buck the snowfall in the Rockies.
If you take I-40 you can cut across the panhandles by taking US-54 out of Tucumcari, NM through Liberal, KS, picking up the Interstates again in Wichita. A lot of it is boring 2-lane going that way, but I never ran into any traffic to speak of. If you are going to drive that section at night, it would be a good idea to fill up in Tucumcari as 24-hr fuel stations will be harder to find off the interstate. I kinda like that route as it makes short work of both TX and OK and there is a good New Mexican food spot I like to stop at out near the NM/TX border.
Main consideration is weather, meaning snow, and traffic. I-15 really jams up on the Northbound side in between the Inland Empire and Las Vegas on Fridays and especially towards the start of holiday weeks. Sundays are the exact opposite for the Southbound side. I avoid that stretch of road whenever possible if traveling during the weekender rush. One more thing if you head north on the 15 out of San Diego. If the map software tells you to take the 215 cutoff towards San Bernardino, don't do it. Just stay on the 15 and loop around through Corona. The 215 is often jammed up with traffic, is only 4 lanes most of the way, and it slows down a lot. The 15/215 join up again below Cajon Pass and I always have better luck staying on the 15 when traveling back and forth to San Diego.
