I have the Alpine 7998 and couldn't be more happier. The seek times are very fast compared to the other mp3 headunits that I have owned in the past. The only Pioneer Premier that I can compare it to is the 740mp. Between the two, the Alpine is significantly faster when loading mp3's.
I am pretty sure the alpine is better SQ wise because that is what ther company is all about. But I am also sure that the pionner is not that far behind
I have owned several pioneers in the past and loved them all but since I purchased my Alpine 7897 honestly it is the best head unit hands down that I have ever owned..period...//content.invisioncic.com/y282845/emoticons/eek.gif.771b7a90cf45cabdc554ff1121c21c4a.gif
940mp, i think is the better choice THough if that Alpine is anything like the Alpine 9815 i was messing around with at the store, than it's a **** good headunit too, but i would still go with the 940mp
