Your entire post is total bollocks.
"The jets are great and their weapons systems make achieving 'kills' easy in comparison with the gun-armed aircraft"
Unless the other guy is flying an equally advanced aircraft, then it is all down to skill again. Duh
"The old piston-engined fighters are a greater challenge to fly well and a whole lot more satisfying; their kills were down to pilot achievement not technology."
No. They fought their aircraft with a tiny number of training hours, therefore were nowhere near the equivalent in terms of skill to todays pilots. Todays aircraft may be easy to fly, but it's not about flying, it's about operating, and todays aircraft require vastly greater capacity and training to operate well. And the idea that technology was unimportant in the old days is simply delusional. ME109 vs Fairey Battle, anyone?
