I have tried a couple of different pumps over the years in various cars.
For SUs the most important thing in making your selection is output pressure. If you select a pump that delivers more than 4 PSI you are likely to need a pressure regulator to prevent fuel overflow and flooding. Virtually any pump you select will provide more than enough flow for a street engine.
The traditional Facet is the "cube" type. You can select the one you want from the list in the PDF linked below. I currently have a cube pump on our GT6.

I installed a Posi-Flo pump in my Mini about a year ago. There have been no problems. I chose it simply because it was what was available locally.
Our Spitfire has the Gold-Flo pump on it. These pumps are more expensive and larger but relatively quiet. There have been no problems. I chose this pump because it was a good deal through an eBay seller.
Of the three, I like the Gold-Flow the best. Unfortunately the Facet web site doesn't appear to have the comprehensive model list PDFs for the Gold-Flo and Posi-Flo pumps like the document for the cube pumps I linked above. If you pursue those pumps, be sure to check the output pressure spec before buying.
I helped install the Carter pump on a TR6 Chump Car. It is a nice pump as others have stated. However, it is higher pressure and we did fit a Holley fuel pressure regulator before the carbs to prevent flooding. This is not a problem but it is an additional expense.
