If you're looking to purchase a program, I would recommend CloneDVD. Since it is still in production, you will receive updates. You will need AnyDVD also.
With DVDXCopy (ripper or no ripper) you can use AnyDVD along with it. But, why purchase a dead program.
I have not used OneClick. Mainly because I am more than happy with CloneDVD.
As for one not being banned: One reason most companies are able to sell their product is because they are in a different country. A country that does not control the sales of a 'DVD decoder.' DVD X Copy was in the US, and was possibly the most mainstream DVD copy program. Also, there were questions about it activating Macrovision without a license.
