The key to having pavers look good for many years is the sand. Make sure that every year or two you get a few big bags of the "paver sand" and sweep it all over allowing it to fill the spaces between bricks. I've done this on a paver walkway and patio for about 15 years now and it still looks good as new. It'll definitely keep the pavers form sinking or becoming uneven.

All that said, I'd never want a paver driveway anywhere where it snows.......Stamped concrete either. I can just see it becoming a PITA to shovel, and will probably end up filled with ice.

Just my $.02
