The Super Nintendo had totally new controllers and was top-loading. The UX was substantially different than the original Nintendo's VCR-style design.

The Famicom was top loading, too.
NES was only side loading because in the US Nintendo was trying to distance itself from the consoles that came before.
Those are very minor 'gimmicks' compared to handheld, touch control, motion control, or hybrid.
