Ideal is a good way to start a debate. The beauty of the old fashioned cup/cone angular bearings is that they're forgiving of imperfect manufacturing,tolerate abuse, and are very field serviceable.

Radial contact bearings are also excellent, but call for closer manufacturing tolerances.

It isn't a matter of better or worse in an absolute sense, but choosing a bearing appropriate to the design, and manufacturing precess of each component.

If you go back to that skf catalog you'll find all manner of bearings, including many specialized designs made to address all kinds of unique situations. None are better or worse, just different.
