It is Ok stuff when done correctly. You need to start with a masonry base like block to get the building to last for any length of time nowadays.
Some companies have gotten out of the synthetic stuff due to lawsuits.
Installing Synthetic stucco also tends to be a location product, I see more in the Fl,CA and hot dry states.
Some very humid counties and states have banned it's use so I have heard.
Whatever you do get a breathable space behind it if you have a wood structure, it helps it to dry out when it gets wet.
Personal opinion....I would never use it.
