Question Varenna, Bellagio, or Another Spot on Lake Como?

I'm planning to stay at Lake Como for 4 nights and I'm torn between Varenna and Bellagio. I've heard great things about both, but I’m curious if there are other towns worth considering. What’s the vibe like in these places? Any recommendations on where I might find the best views, dining, and local activities? Any insights would be super helpful!
