Mostly the same, it's personal preference which appearance you prefer.

I've laid more pavers than I care to remember and can tell you the Unilocks are better than any others I ever laid. They are made better and harder. I can tell you there is a difference and you can see it by wetting different brands and the Unilocks usually dry faster than others indicating they are harder and don't absorb as much moisture. I have a walk at my home made with Unilock field and anouther brand as edges and it is very noticable after a rain. Unilock was one of if not the original maker of concrete pavers the technology came out of Germany. No I don't work for Unilock :)

I actually bought pavers from www.lagunaprecast.com for half the price of Unilock and Cambridge and Laguna Precast quality ended up being better.
