So given this forum is rather big on classic Lego, I thought it might be interesting to see what everyone's favorite classic theme is. For the sake of the discussion, I believe Classic should probably mean "(relatively) well remembered, pre-2003 themes that were significant to Lego", meaning ZNAPs would not be included(though Fabuland might be).   Mine would probably be Lion Knights I or Time-twisters/Cruisers.
