The wind components on the G500 / G600 is, in my opinion, a bit of an odd feature: the displayed wind components are based on chart orientation, in this case heading up. I don't even know how TRK up should look on the PFD part of a G500, with the HSI being below. I guess HDG will (or at least should) be always up on the PFD to have a (certified) HSI.

The Aspen and the GNS430 / 530 display wind vectors. I think that provides a better awareness of wind effect on track and speed at high cross winds, especially when HDG up or on an HSI (which is HDG up).

By the way, a real tail wind component (referred to track) doesn't mean that GS is higher than TAS.
This would be only the case if
GS * (1 - cos (WCA)) > TWC

@ Pat:
Well, I prefer HDG up: since you see the same directions on the MFD screen as when looking outside. This, IMHO, makes it more easy to interprete WX RDR and Stormscope pictures, comparing the MFD with the view outside, at large WCAs. I also like to see the runway at the same position as I see it on the MFD (in my case: GTN 750s), when I get out of low clouds at high cross winds.

However, to follow the magenta line, TRK up is easier. As far as I understand, a good share of Boeing jockeys use TRK up, whereas the majority of Airbus pilots use HDG up. AFAIK, on some Boeings (some 737s, e.g.), the map orientation is only pin selectable. That's at least what they say on pprune.org.
