I got a Kona Unit a few years ago (oh my, it’s been almost 10…). I ended up swapping in a 1x9 drive train. It’s a sturdy and basic bike , you can upgrade as you go. Its almost doubled in price since I got mine- try used?
My Surly long haul trucker has lasted almost 20 years of off and on abuse, and various configurations. If you can find a used Surly that’s in good shape I’d recommend. Also Soma, choose your frame and go from there- spend what you want for the bits that you want/need.
