I think the key problem is the word "EMULATION"

Im no expert as an engineer,but have been into Synths for 20 years.
No,soft synths do not sound like the real thing Period!!
Worst?Better? niether,just different.

As far as the audio plug-ins?not as sure but can for sure hear the difference when records where mixed ITB and OTB. Works for some things and not others I guess. I do still think 2 inch tape sounds like nothing else though.
