Best Marvel Sets?

My wife and I have recently gotten into legos as a hobby that we can do together over the past six months or so. We are quickly learning that some sets are better than others and more expensive doesn't necessarily mean better. For example, the Disney Icon Villains set is a favorite of ours with all the hidden compartments. Captain Rex's helmet is not (kind of just a boring build to be honest).

Anyhow, I was wondering what some of the all time best marvel sets are as we look to find the next set that we want to build! The most important part for us is how enjoyable it is to build the set, but we do also like to display the sets as well. Thank you!!
