Can someone who has knowledge of both explain the difference- other than price and space- between Machon Yerushalayim Shulchan Aruch and Habahir Edition. I currently use the Habahir and am happy with it in all respects. However, I have heard that the Friedman edition is definitely the best. Is it basically more meforshim, and maybe some improvement and corrections in girsa? Any help greatly appreciated.
The "classic" editions of Shulchan Aruch contained many errors - some of which crept in due to confusion between abbreviations, between source text and citation, etc, but most of which are just incorrect citations due to lack of checking.
The Tzuras HaDaf and to some extent Bahir editions attempted to find and correct as many editions as possible. But they did not actively cross-check every citation (a mind-bending proposition on any single page of Shulchan Aruch - try it).
The Friedman did. It just took them some 20 years to achieve.
It would be nice to have a Friedman available (i.e. in the beis medresh, or at a neighbour) if you ever hit a reference which seems to be wrong, but you will probably never notice.
