Glad I could help.
As for the last bit, you like what you like. I'm confident you will notice the improvement of quality, nose, and taste of the Altos over what you've had. That said, it may come to find it's flavor profile not to your liking.
I've had several brands and expressions that though I know they are high quality and well-made, didn't really wow me.
Last night, poured 2 oz of Olmeca, and 1 oz of MV (Margaritaville). Results were the Olmeca is much smoother, and a more pure citrus taste- Aha! So THAT'S what Aguave taste like. As with a good stereo speaker, it gets out of the way and lets the music shine thru. MV covers over the authentic taste. All it does is offer the bite and alcohol flavor, plus a sort of fake sweet cover. The Olmeca is obviously more authentic.
One strange and unexpected reaction from the Olmeca is from my wife. While a lightweight, she can usually sip an ounce of MV with no issues. However, she joined me in the Olmeca, sipping not more than 1/2 ounce, and said the flavor was too strong for her. 10 minutes after that, she was feeling sick. 10 minutes after that she was asleep. She woke up this morning with a left-over upset stomach, swearing off Olmeca forever. I consider that an additional benefit, since it will mean more Olmeca for me. I will donate the nearly-full bottle of MV to her. We can still sip, side-by-side, just different labels.
