Going by bus from Nairobi to Kampala

Not really. If you are just stopping to sleep I don't know how you'd compare the towns.

Strikingstar, it was your telling me in the UG thread about construction and bad roads on the Kisumu route, not Kisumu itself. It sounded like if it were you, you would choose the Eldoret route for that reason. I am used to bad roads in the Philippines. If you think Kisumu is worth the bad roads, I will go there.
