I've got the 5500 and absolutely love it. It works flawlessly with my Samsung Galaxy SIII streaming Pandora on the Pandora input and you get all the control on the deck that you would normally have on your computer or phone like thumbs up, thumbs down, skip song, etc. The iphone will not do Pandora wirelessly on the 5500, an iphone has to be hooked up with the cable. It also works well with streaming music stored on the phone.
It looks like the Alpine has everything the 5500 has and maybe even a better EQ and crossovers. The thing I like about the Alpine is the mirror link for Android that mirrors your phone and lets you use certain apps like navigation on the deck so the phone stays in your pocket. The 5500 has an app mode for iphone but it doesn't work for Android even with ARLiberator. The Pioneer 8500 works with app mode and Android through ARLiberator but even then you have to root your phone and hook it up by a data cable and the 8500 is about $50 more expensive. The Alpine is $100 more expensive than the 5500 but, if the mirror link works like its supposed to, I think it would be worth it. I've always had Alpine decks until I got the 5500 but Alpine didn't have anything at the time that would stream Pandora from Android.
