Sorted after estimated number of hours during 2006:
Jets: Trident 3, LvlD 763, BAC 1-11, DF 727, Tinmouse 732, PMDG 738, VC10, RFP 742 (The top 4 is really close)
Turboprops:
HS780,PMDG B1900, DF ATR 72, HS748 (The HS780 came late but it has accumulated lots of hours in short time)
General Aviation:
DF A36, DF Baron
Others I like alot: DH Dove, rick Pipers Argossy.
The Argossy could have scored higher, but I never seemed to get the grasp of flying it. It's due to error on my side, but the plane would just bite my but* on every second landing.

conclusion:
The HS780 is the best overall release in 2006 in my opinion.
It's followed closely by David Maltbys upgraded Tridents and BAC 1-11, Tinmouse 732 and LvlD 763 the latter ones in no particular order, since they are very close.
My favourite sceneries are VOZ, The ISD airports, The Ai mods from J Vile and FSGenesis Mesh and landclass i no particulary order.
Cheers
