[Tex/LaTex] \emph vs. \mkbibemph and other things

Question

I usually use the commands that come with biblatex (like mkbibemph, mkbibquote etc.) only in my bibliography.

What about using them in the text of my document? Should I do that? Are there any advantages?For example, I remember reading something about that the biblatex-commands can rule whether or not the dot is inside or outside the quotation marks. But I don't know whether this is still the case, whether it works and if it is recommended.

So, what about \emph vs. \mkbibemph? Or \mkbibquote vs. "..." vs. \enquote (of csquotes)?

(I think these are the two commands I am most interested in, but I am sure that there are others that also come with biblatex, isn't that so (e.g. \mkbibparens)? What about those?)

Answer 1

adding

\show\mkbibemph
\show\mkbibquote

produces

> \mkbibemph=\protected macro:
->\emph .
l.6 \show\mkbibemph


? 
> \mkbibquote=\protected macro:
->\enquote .
l.10 \show\mkbibquote

so the biblatex ones are defined to expand to the normal ones by default.
