Pool.. Plaster vs. Pebble tech

[Tom.A]

Looking for feedback on those who prefer Pebble tech vs Plaster. I have never been in a Pebble Tech but I am told it is the new way to go. I just started looking for a future overall and like most things it is an eye opener on cost. I got a quote for 20-24K which included Pebble Tech, new tile and stone coping (leaving current decks). It is a rectangle 40' x 20' plus raised spa. Makes me think I will leave it for another few years.
