Im a great believer in keeping a vintage bike for more relaxed rides on flat routes and having a modern "Endurance" bike for hilly routes. The Endurace bike with 2x11 drivetrain can be set up with wide range gearing and fat road bike tires. The combination of fast rolling tires with extra supple ride at 75-95psi and wide range gearing will keep you happier on longer rides with hills.
