In order, from favourite...

XA GT
AU3 XR6/8 (with the rebel kit)
XC Cobra
Any X series coupe
XY GT
XP coupe
EL XR
EB GT

XD, XE, XF don't do a lot for me, but I'd be happy to own any XD/XE V8.
Pre XP also don't do a lot for me, but as above, I'd own any one of them.
B series do nothing at all for me, perhaps the most boring Falcon ever made.
And unfortunately Ford went for the Camry look with FG.
