Big difference between road bike and gravel bike with road tires?

CruX as only bike

I was thinking about getting a Tarmac or Allez, but I live in Philly and there are some great trails around me. I still want to go fast on the road, but I don’t race and I always just ride alone for the cardio so I’m fit on my motocross bike. Would I be happy with the CruX, assuming I ride 70 percent on the road and 30 on trails? Thanks!
