We bought Universal APs in lieu of Disney. Universal is theoretically a good value, and there are many things about their parks that I like. The theming in the Potter lands, Simpsons, Seuss etc., is a lot of fun.
But...it's just not quite as good. They are missing just enough "magic" to make me still wish I was in Disney world when I am in Universal.
All else being equal, I'd still rather have a Disney AP (or both, if I can afford it) but, of course, all is not equal. I'm waiting to see what Disney will do as far as pricing and access restrictions. If the price seems "fair" and I can basically go when I would want to, I'll buy Disney passes for my family.
If not...well, it pains me to think that I will choose an "inferior product" over money. True, I've been doing that my entire life: almost everything I've ever bought has been a compromise. But when it comes to entertainment and luxury, if your purchase doesn't truly make you happy, then why bother buying it at all?
