Well, once Germany became relativly lax in its "who do we export our weapons to" regulations, quality of new developments significantly increased.
The Leopard 2 for example was, until the 2A6 version, slightly inferior (duel situation, this tanks never faced of in battles) to both the M1A2 and the T-90, however the continuing demands from the quite numerous countries using Leopards enabled the relativly small KMW arms company to catch up and even surpass current Russian or US technology on the ground.
Leopard 2 based advancements were also used in the construction of the PzH2000, the most modern SP Artillery Howitzer today.
As the only competitor coming close to it comes from Russia (bear in mind that the current state of the art Russian artillery system is also a generation or 2 ahead of the American M109, the Russians have a good system, but beeing Russian rules them out for most Nato countries), the PzH will propably become an other significant success like the Leopard 2.
I was an Artillery jock so I am propably biased, but in the case of a limited conventional conflict like in Georgia, Americas inferiority in Artillery may cost them a lot (well, a single PZH2000 has the firepower of 4 M109, moves faster, has to be hit directly to be destroyed, has MRSI and excellent shoot and scoot capacity... Well, it also weighs about as much as an MBT but you cant have everything), especially if modern and competently used ground based air defense systems hamper their aerial superiority.
Turkey did order 116 F-35, with currently workshare of Turkish firms being somewhere at 6 Billion $. Very likely Turkey will order even more replaceing the F-4's in the inventory, they where modernized in the last years together with workshare by Israelian Aerospace Industries, but at 2020 this old airframe will be out of service.
The Turkish Armed Forces has initiated a $160 billion (excluding the yearly military budget) modernization program in 1997. $45 billion is earmarked to go to the overhaul of the Turkish Air Force.

In the next decade, as orders currently stand:
116 F-35
240 F-16 CCIP
52 F-4E 2020 Terminator
104 F-4E Phantom II
39 RF-4E Phantom II
43 F-5 2000
The Turkish Airforce will not order any Eurofighter or any other aircraft except F-35.
Eurofighter offered Turkey 9 Billion $ workshare for Turkish Industry, if Turkey orders 120 Eurofighter.
Turkey Receives Final Offer for Eurofighter Typhoon
Economically, participating in Eurofighter project is better. So if Turkey does reject Eurofighter and goes for F-35 instead, it means F-35 is the best option available from view of Turkey, haveing the expertise of being one of the largest Airforces in the world. F-35 will be the workhrse of Turkish Airforce in the next decades.
Off course F-22 is better, but it is not available for export. F-35 is anyway good.
