gIzzE, I think there is no question that the Logic 7 is better than the Alpine upgrade - more speakers and higher power outputs as well.
I think it should be compared to the HiFi or BMW Business option instead and I suspect that the BMW business version spreads the power to front and rear whilst the Alpine is only for a front seat sound stage - something I always previously thought I would dislike.
As for comparing the Alpine upgrade with the standard system, it is way better as a lot more power goes to the under utilised subs and there is more meat from the front door speakers whilst the addition of the front tweeters is absolutely essential.
