IMO, the component differences are a wash, neither kit has parts that need to be replaced. Looking at the geometries, both have ~72* head tube angle, the Trek has more fork offset/rake so it'll handle a little quicker. LHT also has lower bb drop and longer chainstays, adding to more sluggish handling compared to the Trek. The geometry differences are subtle, many riders will not notice or care.

IMO, the real difference is sloping vs horizontal top tube and head tube length. I didn't get a Surly LHT Disc because I wanted a long head tube and sloping top tube. I went with the Soma Saga Disc (now the Soma Saga DC) for the higher stack and sloping TT, I would have bought a Vaya but there weren't any framesets. I'm an old fart and I hate having 100mm of spacers, I have enough Fred in me as it is.
