As much love as the "synth era" gets, and even with the added boost of Signals, I'm confident that the late '70s/early '80s era is going to win this in a landslide, and I expect that the eras other than these two will get very few votes.
My ranking would be
1. Kings through Pictures
2. Rush through 2112
3. Presto through T4E (despite the existence of RTB)
4. VT through CA
5. Signals through HYF (poor Signals)
P.S. I know someone explained the "sector" thing a while back, I have no recollection what it means.
