A basic concrete drive will be much less expensive than pavers. Repairing a cracked drive by attempting to fill the crack and overlaying with stamping will not fix the problem that caused the crack in the first place. If the crack was caused by movement, it's likely additional movement will occur with time, so any "quick fix" will simply be just that, quick, short lived and a poor investment.
Pavers can work on steep driveways, but you need a very strong curb to be put in place. Often times they put in a 12" wide concrete curb, and then lay pavers between the curbs. The advantage of pavers is that if you get movement in the future, you can repair just the location where the movement occurred, often times at much less expense than a total replacement. But the initial cost is quite high compared to new concrete.
Here in Austin, the current replacement cost for a driveway runs between $5 and $9 a square foot, including removal of the existing driveway.
To minimize cracking of your new concrete driveway, make sure the contractor breaks up the pavement with more expansion and control joints. The control joints are designed to focus any cracking into the trough that's created by the control joint. Expansion joints are designed to allow the concrete to move/expand with temperature changes. The more of these you have, the less likely it is that you will get cracking across the face of the driveway.
You may still end up with issues, even with more joints, hence one of the benefits of pavers, but there are limits to any design, and your slope could be pushing any available options over the brink.
You need the adivce of someone who is experienced and does great work and who can give you some realistic options.
