My Ogre runs 622 rims (700c) and I use 34T chain-ring and a 16T sprocket on the hub.
This offers approx 17.3 to 90 gear inches.
I'd prefer a little lower but I'm at the minimum to keep within warranty already so will just have to harden up.
I've been not riding for a while and am unfit so struggling a little on the hill work even with the 17.3 gear inches.
I'm yet to use top gear but have spent a lot of time in bottom.
I think the Rohloff is a bit of a pig being heavy and uncrisp in gear changing especially compared to my other bikes Sram Dualdrive.
However I have little interest in derailleur maintenance and it is for this reason I appreciate my "Hoff" most.
As a utilitarian piece of equipment I value it highly.
