I've both in AK and AR versions and can make a case for either.
L to R:
Zastava PAP M85NP 5.56 pistol with SB-47 brace, uses AR mags.
Mini Draco 7.62 SBR with ACE side folder stock.
QuarterCircle 10 Glock mag 9mm AR pistol with SB-15 Gen II brace.
CMMG 9mm SBR with MagPul CTR stock.
For the AR you save maybe $100 with the brace compared to building the same thing without the brace and paying the $200 NFA tax since the brace and extended buffer tube runs about $200 whereas the CTR and MilSpec buffer tube runs about $100.
For the AK the savings are better since the SB-47 runs about $125 and the stock and mounting hardware start around $200, add in the NFA tax and the AK version can be almost $300 less expensive.
For an AR, if you live where the LEO sign off is no problem, or you are have a trust for suppressors (or plan to) the SBR route would be my recommendation.
For the AK since the potential cost savings are greater, it pretty much depends on how much you want a folding stock or prefer the "cleaner" look of the SBR.
We've had these out with a variety of shooters, experienced and inexperienced and all agree there is no significant difference when shooting unless you like the CTR stock fully extended. However all would prefer getting the SBR until I explained the NFA requirements for doing so.
