It has more to do with the sealant than the AIO, but Jeffs products look better to me, and I think they are easier to use, though it might be just that I'm using Jeffs stuff now and I'm getting more experience with it. Klasse, when viewed from a high angle, can seem like it has a silvery sheen on the surface. It's the only LSP I've seen do this. Jeffs doesn't do this. Other than that they're both good sealants.
