I have two bikes, one of each. I have a Specialized Diverge gravel bike with 700x38 tires and a Cervelo Caledonia with 700x30 tires. Both are good road bikes and I ride them interchangeably when riding solo. When riding with a group, I'll take the Caledonia because it's faster. When riding off road I'll take the Diverge. Riding on pavement by myself, both are equally enjoyable. If I had to keep only one, I'd keep the Diverge, the gravel bike. The Diverge is very good as a road bike.
