I’ve been on a specialized diverge alloy for 2 years and about 2000 miles through every type of terrain imaginable and it rides strong. Never had a single issue. Pathfinder pro tires will likely be a good bet if you’re mixing gravel and road. My next bike will absolutely be a diverge.
I’d go 1x with a big cassette in the back if there are hills/mountains where you live. The new sram mullet drivetrains are rad.
