what is the most Desirable A body line

When I hear 340, I think 69 GTS. My first was 340 auto with 3.91 rear, good car. My next 69 GTS was a 440 auto, not a good car, I didn't like it.
Then came my 71 Demon 340 auto 3.55 that I liked the best of the three. I like the looks and the improved aerodynamics. Less wind noise too.
But I see the 69 GTS 340/auto/3.91 as the ultimate usable low buck hot car buy in back in the day.
