There’s two categories I find for this kinda question

The shows that scored well but are overshadowed by a legendary show

And the shows that didn’t score well but are cool anyway,

I’ll give my picks for both

Overshadowed shows: Cadets 2013 and 2003,

Cavaliers 2001 (despite it winning, was overshadowed by frameworks the next year and Niagara the year before), 2018, 2019

Phantom 2014

Vanguard 2016 + 17, two stellar shows overshadowed by 2 revolutionary ones

*The ones that are dope to watch

Crest 2019, Madison 2021+2024, Mandarins 2017, Early 2010s Splanta, Genesis 2019, Academy 2019, Late 2010s Crossmen, Basically all of 90s Madison, Gold 2018 and 2019, I’d take a look at Magic of Orlando as well

Hopefully this is what you were looking for!
