Hi
Seems to me you are talking Apples and Oranges.

Luckily I own, the PTIEP, all of the EW Libraries, and M5 3.

PTIEP: Love Strike and Hybrid except that the AIR VI's start causing problems when you open up to many instances of the plug-ins.

Mach 5: I think it's a much more complex and deep sampler then Structure plus it comes with an awesome assortment of sounds.

East West: If you are looking for scoring it's great. got Platinum Orch, Symph Choirs, RA, SD2 etc.

If you are doing Orchestral Scores PTIEP won't help you.

I'm not big on the NI GUI's. I find them very PC as in a Windows type interface which I find very annoying. The VSL sounds included are limited.

I don't think there's one that does everything.

Good luck...in the end it all comes down to budget :-(
