Kone versus Otis on the same job last Tuesday, which unit actually delivered?
We had a machine room replacement last week at a 12 story building in Chicago. My crew prepped for a Kone MonoSpace, but the building manager insisted on Otis Gen2 because of some old contract. We had both units on site for comparison and testing. The Kone started up smooth with no load, but the Otis handled worse vibrations after we added counterweights. Has anyone else run into a similar showdown where one brand's specs lied on paper?

Stick with the Kone. Otis rides rough when it matters.

That's a solid point, Barbara. I've seen that same pattern play out on retrofit jobs in older buildings before. The Otis Gen2 seems great on paper with its belt design, but once you get the cab loaded and running, those resonance issues start showing up bad. Kone's MonoSpace just has a more predictable ride quality across different weight loads, especially in buildings where the rails aren't brand new. Your mileage may vary based on how well the guide rails are aligned, but my experience leans Kone for anything over 10 floors.
