Honestly all treadmills at that $1300-$1800 price point function near identically and have similar if not identical grade parts.
None of them will/should ‘die’ early, they’re all pretty solid.
That said, a regularly used TM in this price range lasts 8-10 years before somethings need a fix. Often times it’s the deck (wooden board under the moving belt), sometimes other things, and that’s when having the right brand helps, as a known company like Sole has tons of experience helping their users fix/replace stuff that breaks.
That said, my Sole F80 is now 9 years old, and lives in a very harsh environment garage (AM condensation is a real killer) and have replaced nearly the entire unit outside of the (rusty) frame - deck, motor, console, etc. So it’s not bulletproof, and yes, it’s annoying to have to do this stuff - not hard, but not so easy that you can do it in a few minutes. Sole provided parts very quickly and had phone help that was also useful, but I was still own my own for most of it. (Thanks youtube).
It’s really what happens AFTER things go wrong that you’re paying for, not just performance up front. You don’t get a ton more of a quality run experience on a $5k Landice, nor does the frame look ‘that’ much nicer, nor is the console signficantly better - but the internals will definitely last longer AND if things break, their warrantee will be a lot better and longer than the $1500 TM.
In summary, when comparing TMs in your price range, you can almost ignore the features stated - they’re all good, all will go faster than you will ever run, and all have motors that should outlast you (most of them are lifetime motor warrantees, despite Lionel killing them regularly.) But you absolutely should go over the warrantee and replacement terms with a fine-toothed comb, as that’s where you’ll feel it the most.
