For me, the wedding band is the sentimental part of the wedding set. Afterall, its the token he gave to me as we exchanged vows and committed ourselves to one another. I don't see myself ever trading in/upgrading/altering my wedding band. But as for the engagement ring, well, we're not engaged anymore, we're married. So, to me, the e-ring symbolizes passion and romance, while the wedding band symbolizes love and commitment and family. And hey, the more passion the better, right?

I say upgrade the engagement ring if it isn't exactly what you want. When I was first engaged, I was certain I would never want to upgrade, and now, less than three years in, I've already upgraded twice. I guess time changes things. Good luck deciding.
