As far as a side by side comparison, neither is better. If your looking to buy a graphics card from them, post the ones your interested in so then they can be compared. Both companies offer better graphics cards at different price points.
If you mean which makes the best high end product, Nvidia currently has the highest performing single graphics card but ATI isn't far behind
And by the way, Nvidia is the company that makes the Geforce series of graphics cards and ATI makes the Radeon series.

Performance-wise, the GeForce 9800 GTX should in theory be a little bit better than the Radeon HD 4850 overall (about 10% faster).The GeForce 9800 GTX is much (more or less 47%) faster with regards to texture filtering than the Radeon HD 4850.The GeForce 9800 GTX will be just a bit (more or less 15%) better at full screen anti-aliasing than the Radeon HD 4850, and should be capable of handling higher resolutions more effectively.
