They're both expensive, but we've switched over to Universal exclusively (as opposed to splitting Orlando vacations between WDW and Universal) solely because of how disproportionately complicated, costly, uncertain, and generally miserable Disney has made the touring/queuing experience.
At Universal, we have the choice between waiting in fairly reasonable, or at least predictable, standby lines (so long as we don't visit during major holiday or vacation periods), or else enjoying fast Express Pass lines at every single attraction save one (included for the whole family when we stay at a premium hotel at passholder rates, with seasonal annual passes that cost only slightly more than a 4-day ticket). Either way we do it, with minimal planning and a reasonable amount of park knowledge, at Universal we can enjoy a relaxing day with some room for spontaneity, and no need to engage in any up-charges or pound my phone all day instead of having fun. (*Hopefully, this won't change overmuch when Epic Universe opens, and I won't have to rescind this assessment!)
At WDW, we face the Sophie's Choice of accepting unreasonably long and unpredictable standby lines, or paying tons more to gamble on the possibility of having a few shorter waits at a handful of attractions, none of which are guaranteed to be available in the first place, and only if we arrive during set time windows that may or may not be convenient for us, or spend hours on the app, trying to continually modify and upgrade our reservations so that they don't disrupt our day more than they're improving it.
I realize that Universal's roster of attractions isn't as appealing to some, and that it doesn't have the nostalgia factor that WDW does, but for us, we enjoy the Universal touring experience enough that we're willing to pay the price for it (which, after the purchase of seasonal annual passes and discounted premium hotel stays, comes out to 20% less than the rough Disney equivalent of 5-day parkhoppers and discounted DVC stays with rented points). WDW doesn't even enter into our vacation discussions anymore -- which is sad, because the vast majority of our family vacations there -- up until the last couple -- were among our happiest memories! Obviously, our experience and opinions are subjective, and I'll be the first one to admit that our priorities have always skewed toward how many good rides we can enjoy with the shortest wait, rather than on shows, dining, or other bigger-picture factors, but we feel like Universal is still offering a product that's worth investing in.
