You might consider the 150. You can upgrade to Ultegra as an option. The 150 is smaller diameter straight gauge tubing, as opposed to the oversized butted tubing on the 250. I've had a Peloton (150 predecessor) for several years and discussed this with Lynskey at the time. IIRC, the 150 will be lighter because of the smaller tubing and will have a more compliant ride. I specifically asked them which bike would ride most similar to steel. Anyway, they are a great company to deal with. Bikes are made in USA, if that matters.
