"Just like what I mentioned above about every dash having it's own thing. Here, it's that every stun has it's own thing. Riven has short cooldown. Jax has immunity to AD carries. Sion has range. Renekton has autoattack reset and (if it's empowered) more than twice as high a scaling as Riven has (just try it once. AD Renekton). Leona simply has a lot of them. Shen has dash + AoE. Etc etc etc etc. 

Jax's stun doesn't have "immunity to ADC", he's just immune to AAs. You can still CC him, magic damage him, AoE him, etc. The CD is 18 seconds and has nearly double the CD of Riven's for the entire game at level one and it's a lot less slower casting than Riven's since you're claiming it's already a slow cast. The only reason I compared Riven's stun to Jax's is because of their AoE nature.

Sion is single target, Renek is single target.

And Leona fulfills a completely different purpose in the game...
