The truth is there is no single best hiking route on mount Kilimanjaro that works for every trekker. For example, if you really value the scenery, then the Lemosho, Shira, Northern Circuit, Umbwe and Machame routes probably offer the most scenic and diverse landscapes.
However, if better acclimatization is a priority for you, then a longer route like the Northern Circuit is the best choice.
If you want the shortest (i.e. steepest) route and are used to high altitudes, then Umbwe may be a good fit.
And, if you are averse to crawling into a tent, consider staying in one of the huts on the Marangu routes. These come complete with beds and sleeping huts.
