Most of the AirForce platform is kind of like Legos, snap them together how you like, with the Texan being "one size bigger." There are enough options I don't remember them all, so please pardon me if I'm incorrect in a few spots.
If I remember, the Talon has a smaller barrel, bottle, smaller valve, shorter receiver, is lighter and has less power. The Talon should have enough power when shooting paper or most any small game. If it's really windy you might want a longer barrel or the larger valve of the Condor. Hand pump folks might want to use less air (Talon). AirForce does update the designs so I may be off some, but it should give you ideas of what to look for.
Power-wise I *think* Condor can be stepped down to be like a Talon, but the reverse is not true. Weight wise I *think* a Talon will always have a lighter receiver, but that might be the Talon-P (pistol).
The suppressed barrels are shorter than the non-suppressed. All AirForce airguns are single-shot-only, no magazine, except for their R.A.W. line.
Hopefully most of that is accurate--if not douse me in whiskey and have a redhead feed me hotdogs.
