I would say go ahead and buy whichever one you prefer, Dave. I've just had a quick flight in both of them in FSX. My preference would be the Prowler, as I like the VC more on that, but they both have very nice FDs (I actually stalled and crashed the Intruder...

) and the exterior models are excellent. The animations are great, too.
The one downer I've found is that both cockpits have blurry text labels in the VCs. This is worse for the controls that don't work, but even on the dials, there is a bit of fuzziness when zoomed in. Shame, that, but the rest of the models are good enough to make that bad point worth it.
The 2D panels are up to snuff.
I took loads of screenies and it's difficult picking out the right ones to post, but hopefully these will be of use - remember, they've been resized, so there is a little more fuzziness in the VC than is actually present full-size.

Oh yes - the wings are not visible, looking back from inside the cockpit. That may have been a "no wings from VC" model - I'm not sure.
Here's the Prowler VC:
...and the same blurry labels:
You do get some nice instruments such as a weird artificial horizon/flight director type thingy (there is a manual!):
-and a GPS type moving map job:
You also get comprehensive kneeboard checklists and reference info with both:
Doesn't it look purty
Note the moving control surfaces - the long flaps in front of the flaperons go upwards as the main surface goes down, too:
Yes - go for it, mate - I doubt you'll be disappointed - Virtavia might even have improved things, since these are the old Alphasim models
