Oh, I like this topic.

My favorite of the '80s is Maskman, by default, as it's the only '80s sentai I've seen. But overall I'm not a huge fan of it.

My favorite of the '90s is Jetman (even though it feels more akin to '80s Sentai than any '90s Sentai that came after it), but it's close. I freaking love Kakuranger, Dairanger, and Carranger too. And I still haven't finished Mega, Ginga, or GoGoV, so this could always change. (But honestly, I don't foresee anything upsetting Jetman from the top spot... I just love that show so much.)

'00s Sentai is kind of a weak spot for me. I've only seen Magiranger, a little bit of Abaranger, and Shinkenger. Shinkenger is the easy winner of that decade, from what little I've seen.

Obviously '10s Sentai is still ongoing. I love love love Gokaiger, so that's the current one to beat.


As for the nitpicky time stuff... I think we measure decades differently than we do millenniums/centuries. Decades are less formal groupings. Like, yeah, 2001 is when we enter a new millennium. 2101 is technically when we'll enter the 22nd Century. But for decades, I've never heard anyone be like, "1990 man, that was the best year of the '80s." That just doesn't make any sense when we informally refer to decades as "The '70s, '80s, '90s, etc..."
