We spent New Years at the Valentin Imperial Maya 4 years ago and loved it. Actually we had so much fun we bought my parents a trip there for their 30th anniversary later that year.
We have stayed at Valentin Imperial Maya 4 times. The landscaping is gorgeous and even at 100 percent capacity it never feels crowded due to the large footprint. It should be noted that the Valentin Imperial Maya is less price wise than Secrets Maroma and Excellence (and therefore a step down in food; however, it still is very good).
Honestly, I don't think you would be unhappy with any of the resorts you have listed. Tripadvisor reviews and photos by people who stayed at the resort are very helpful in deciding.
