This is like trying to convince a dyed-in-the-wool Democrat that Bush is a good president... not gonna work very well!
I'll just say that while IOA is Universal's best effort to date, it still falls far short of the Disney standard in every meaningful way except thrill quotient. USO itself is quite ordinary (and I'm being generous). So I'd dispute your math: Disney has 4 outstanding parks while Universal has one that's okay and another that is downright poor.
But to each their own! Enjoy those suites!
