I have not had either so I can't give you a first hand taste test.

P.

I now have a limequat that is 4 years old and is doing very well. I have more limequats that I know what to do with them. It just keeps producing and producing. I have it in a large plastic pot I got from Costco. During this winter, I moved the pot to a covered porch and just lost a few flowers and now I see a bunch of new growth and tiny blooms. I am certain you will enjoy these wonderful trees.

Thanks for the help,and the links. I think I'm going to go with the limequat. Carino do you know what variety you have?
