Which is better: Renaissance Esmeralda or Championship Hyatt?

They are both pretty nice. Right next door to one another. It would depend on what you are looking for. Are there features that you are interested in that one might not have but the other does? I've stayed at the Esmeralda but I can't say that it would meet your needs since you did not list the amentities you would want that would make if preferable ove the Hyatt.

Can you provide more info?

I would take the Esmeralda over the Hyatt any day. The best thing about the Hyatt is the spa, which is really pretty good.

The Renaissance is gorgeous. I keep a picture I took from my balcony looking over the pool, palms and mountains on my desk at work for stressful moments.

The Esmeralda is very nice! The setting is nice and the rooms are huge!
