I have 5 taps and they are all 575's. they work just the same as the 525, but if you want a little more head on your beer, it does that nicely. I have a caramel vanilla ale, duvel clone, milk stout, red ale and root beer on tap right now. I've used the creamer on all of them. Like I said - it just makes a nice head and gives you a little extra carbonation for a few minutes
. I'd keep it - why not?
