RonZ definitely has a muskier palate compared to Zaya, and it's a bit more complex in flavor as well. I do keep a bottle of both on hand as they are both very good rums. Second the El Dorado recommendation as well. The Dorado 15 yr. is also very good and may be a bit easier to find at your local store. Also, if you can find it, HC Cuban Barrel Proof is probably the best I've had. Surprisingly smooth for its alcohol content. Profile is similar to Zaya, though a bit less sweet, but much smoother than the HC7 or RonZ.
