To use the LGEO library will give you nicer render as the parts have been redesign to be more pov compliant.
There is also the ar library which can be useful for some parts, but personally I don't like how those parts have been modeled.
Problem is than LGEO development is currently on hold (if not dead) so there are a lot of parts not handled by it. Then if you want to dig into it you can still have the ability to create you own LGEO parts and add them.
I you care about high quality renders I would advise.to use LGEO, if not keep with the standard Ldraw files which will still give good results in povray anyway.
