I’ve been through this process and seem to remember that very little is actually taller or shorter than an Arkose (or, for that matter, a Defy, a Roubaix, a Synapse, a Datum, etc. etc.). Stack heights all seem to hover around 600mm for a large size.
Lots of steel touring style bikes are probably shorter and taller (Salsa Vaya being one) but heavier etc.
The Giant Anyroad Comax looks like one of the best bets, taller and shorter than most but lighter and faster (I assume) than a steel tourer.
Apparently the GT Grades are taller and shorter than average too, there’s something weird going on with the geometry numbers but an XL barely gets any longer but gets 3cm taller at the front, nicer looking and nicer specced than the Anyroad but apparently massive standover.
Anyway, I gave up and just got a mountainbike again, haven’t got the time for any meaningful road rides anyway…
