We use Hydrazzo quite a bit. It's a polished finish which brings out the colors and provide a smooth surface much like a shark skin texture. Not slippery but some grip.

It's a 2 day process. Plaster applied the first day, the second day the finish is exposed with acid and then polished.

My recommendation on any plaster finish, is to truck water in when completed. You want that surface to be hydrated as quickly as possible as it's part of the curing process (28 days).

I'm not completely familiar with the Pebble Tec finishes. My plaster contractor has plastered 1,000's of pools over the years and I go with his expertise and recommendations on certain finishes. We have had good experiences with Hydrazzo for the last 10+ years.

Like any other plaster, the key to longevity is chemical balance right from the start and constant monitoring and adjusting going forward. Most plaster failures are due to chemical negligence.
