Glad you had a great time.
I was always a WDW fan and just never had any interest in Universal. The year Harry Potter was supposed to open, the opening date was announced to be that spring and Universal also offered those park to park 7 days for $99.00 tickets. It was just too much temptation.
I made reservations to stay at WDW for that May, with plans to check out Universal a couple of days, just for Harry Potter.
As you know Harry Potter didn't open until mid June that year, so I missed HP, but decided to check out Universal anyway, since I already had those 7 day tickets. I was blown away. In fact, I loved it so much that the very first day I upgraded my 7 day ticket to an AP and have renewed that AP every year since. I came straight home and booked a trip for just three months later for an August trip for Universal and that trip never even made it over to WDW (even though I had an AP for both). I tend to spend more time at WDW, but also try to make it over to Universal for a few days every trip. I love both parks.
