Default NavWorx ADS600-EXP and Class B airspace

The ADS600-EXP deal this week seems pretty good but:

How will an ADS600-EXP system with: NavWorx external mounted antenna and GTX-327 transponder show up on an ATC system as compared to a fully TSO’d ADSB-out system?

One of the technical FAA guys at KOSH last year was trying to warn me about the “quality” of the ADSB-out system and how they may show you differently on their systems based upon the performance. The point being communicated was you may be treated differently in airspace as a function of how you display (even if you have ADSB-out broadcasting enabled)...

Here are my concerns:
Sec. 91.227 Automatic Dependent Surveillance-Broadcast (ADS-B) Out equipment performance requirements.

According to this requirement, we need to be looking at the following technical parameters when evaluating any purchases of ADSB out options:

(ADS600-EXP Specifications):
The ADS600-EXP is a Remote Mount ADS-B Transceiver with UAT OUT & IN, for use by EXPERIMENTAL AND LSA AIRCRAFT ONLY - Not for use by Certified Aircraft..

Experimental and LSA aircraft equipping with the ADS600-EXP are "good-to-go" for entering airspace mandated to have ADS-B on 1/1/2020.

Complies with the ADS-B Final Rule Technical Amendment, dated 2/9/2015, affecting 14 CFR 91.225 (b)(1)(ii) which permits ADS-B OUT in the National Airspace with devices that meet the performance requirements of TSO-C154c.

Transmits SDA = 2, SIL= 3
I don’t see anything about NACp, NACv, NIC etc here? It all comes down to how good the GPS position source is doesn't it?
