Lake Garda vs Lake Como

We’re planning a semi last minute honeymoon to Europe for late March / early April of this year. We’re set on doing Rome and then Florence but after that is what we’re still working out. We initially thought Lake Como but after doing some research, I started looking into northern Lake Garda.

Has anyone been to one or both? Looking for all opinions and thoughts.

For context, we’re thinking of 3 or 4 days and using it as the more relaxed portion of the honeymoon compared to Rome / Florence. We’re not renting a car so we would need it to be accessible by train and have plenty of restaurants and things to do walking distance.

Thank you!
