Welcome to the club
What spec and wheel size? This is likely to influence your impression as much as anything else. I've been a fan of the Rohloff since my first in 2003, but it doesn't make the bike, I never really gelled with the first one I had it in.
Was the Genesis an Equilibrium? Nice bike, I'd be inclined to agree with mickeg about keeping it for the contrast, though there may be reasons you can't.
On any day ride, I ride as fast on my Mercury as I have on any bike I've owned (Which has never been that speedy) and that includes some Sportive/Audax bling bikes, though never an out and out road bike. It's only on shorter rides, maybe up to 50 miles but more commonly 20, where I've been faster on other bikes, I do sometimes miss having one, though not often enough to do anything about it.
Give up Strava
I like to record everything, just love the numbers, and a record of routes, Strava seems as good a place to do so as any. Though it's easy for it to become a master rather than a tool, I felt this was happening a few years ago and temporarily turned my account private, doing so broke the competitive element.
Have fun on the new bike, plenty of opinion on this forum, not all of it in agreement which is a healthy thing, please do continue to add yours and looking forward to the photos
