Personally if you intend to do a bit of gravel that does not required a CX bike, clearance for 32mm tyres and mudguard can make all the difference if you don't mind the retrogrouch appearance and canti/mini v.
The 51cm reach will be slightly shorter than measured due to it's slack seat tube (in-line post needed).
Another option is the Velo Orange Pass Hunter.
