Name some equal and opposite yoyos

I was wondering what people think are some pairs of yoyos that are similarly priced, but play totally differently from each other? Not so much good vs bad, but stable/skittish, solid/light, whatever you use to distinguish play. 1A, 2A - anyA, just throw some out there…

Gnarwhal is kinda the opposite of the Cliff cause one is oversized the other is undersized and the Cliff has a crazy shape and the Gnar has a less angular shape and kinda organicish

Flipside and onestar

Go Big,

Loop 1080

Big Yo x3 (same price range)

Mighty Flea

Smooth move and karma play quite similar to each other imo.
