The best era is not listed in the poll, which is 3000 to 3030.
I picked 1551 - 1580.

Bach won for me.

What if my desired 30 years goes from the middle of one of yours to the middle of the next?
Wait a minute! All those thirty year chunks had really interesting music in them. And some really awful music, too, I suppose I should add.
But there's no "All" (or banana) option.
Anyway, since inevitably the music in any given chunk is different from that in many, most, or all of the other chunks, it is conceptually impossible to assign "best" to any of them.
I tend to spend most of my listening time in the last twenty years (only half of which is on this chart), but I still wouldn't choose that as "the best." I like the approach articulated here, in a novel by George MacDonald, a conversation between a raven and the main character:
Vane: "Am I wrong in presuming that a man is superior to a bird?"
Raven: "That is as it may be. We do not waste our intellects in generalizing, but take man or bird as we find him."
I voted 1850-1880, a certain German opera composer's mature years...
If I would have been serious, I would have voted when Beethoven's late string quartets were written, but I think Beethoven is like the Classical God & Elvis is the Rock God, so what's the difference? (apart from the very important fried banana sandwiches!)...
Honest differences are often a healthy sign of progress - Mohandas K. Gandhi.
1881-1910 - Mahler clinched it for me.
