I suppose it all comes down to what people are looking for - I've been going to Disney all my life, having made many trips to WDW and a healthy handful to some of the other Disney parks around the world, and have been to Universal Orlando twice. Once shortly after Islands of Adventure opened, and once shortly after Diagon Alley opened. I enjoyed myself both times, but there was plenty I found underwhelming, and while I've found myself in recent years wanting to spend less time at Disney I haven't found myself wanting to spend any more time at Universal.
I'm prepared to give Epic Universe a try when the day comes, but I'm not particularly interested in much of what is rumored for the park. I think I'm just not someone who's interested in the flavor Universal has to offer. And it frustrates me to see Disney more and more trying to alter their own recipe to try to stick it to Universal instead of just doing their own thing, which worked for so long because the flavor was so good.
It sometimes feels like they're trying to reinvent the wheel when all we want is for them to soup up the car and repave the roads.
