Out of the routes I have ridden, the Silvers are by far the most boring, especially in Georgia and North Florida. The most boring stretches in my opinion are Savannah-Jacksonville and Palatka-DeLand. To me, any scenery can be interesting if it is changing. Every mountain and urban area is different, so those areas never bore me. Meanwhile, except for in populated areas, much of the route in Florida and Georgia looks identical. I could see deserts or farmland being boring too, but I have less experience with them. Although I have been on the CL/LSL from Cleveland to Chicago multiple times, it is not constant farmland as it has urban areas, industry, and some water views, so that doesn't bore me. When I went on the CZ and EB, the farmland is covered in snow which made it very interesting to me; I don't think there's much better than riding a train through snow. The only experience I have with deserts that weren't at night was the CZ in Nevada, which could get boring after a while but had some interesting aspects such as the distant mountains and tiny towns. I found it very scenic as we got close to Reno with the skyline, Sierra Nevada Mountains, and even a few wild mustangs.
