I was worried that I'd regret not having it, especially given that I've had nice aftermarket systems in the past. But I've gotten used to the stock system and definitely don't hate it. It sounds like for your needs, it will be fine.
If I had it to to over again, I would absolutely get the premium because I like the idea of having the best OEM system and I dislike the idea of going aftermarket on a BMW.
