We just went through this whole thing. Stamped is cheaper than pavers
Stamped - $4600
Pavers - $8600
stamped can crack
it is slippery (liability issues)
I have a friend who has stamped (whole driveway, all walkways, and patio), it is crumbling and falling apart. It is less than 2 years old. I was also at a resort in the Dominican Republic and it is super slippery when it is wet. I mean, sliding in my tennis shoes!
There are downfalls to pavers too.....
We ended up with pavers! The key is to find a guy to do the pavers, but buy your own supplies, saves a ton!
I don't have a picture right now, but will post one, I think the look of ours, blows what stamped could have done.
