Which would you do? What are the pro's and con's of the two
configuration?
For this project I am using SS rectifiers. Were I using a tube rectifier
I would go with the center tap, of course.

Here is a similar circuit but this time with choke input to filter. You can see the SUF (& PUF) have gone from 0.586 to 0.883. All these numbers are ideal & the best possible. There will be other losses in all, but this gives one an idea of what is possible. Some 3-phase circuits are quite a bit better, another reason 3-phase is in common use for any large power requirement.
