The way I look at it on a cx bike I ride mainly two situations:
Road (with a some paths, tracks and green lanes) – touring tyre
Trails (with some paths, tracks and green lanes and a pootle on some tarmac) – cross/mtb tyre
The 'faster' cross tyres that claim to work on the road are fine (but perhaps not so fun) for the 2nd situation. They're fairly compromised for trails and even dry racing. They are pretty good for cx sportive type-events if you're going for an overall time. If the cross tyres seem hard work on the roads you can always HTFU and pedal harder.
