Great Question! Not as easy to answer as it seemed at first glance. I think there was a wider range of options in the 60's, more creativity, more differentiation. Today, there are echoes of the past, but they are all very similar. Also, they are safer, and there are some really cool gadgets. They are ****** difficult to work on now, perhaps way too many electronics. If I had to pick one and only one, it would be the 60's.
