I've tried Halo Top (and, in fact, have more in the freezer for one of the Christmas meals we've been invited to), Rebel (once), and Aldi's house brand.
Of them all, I liked the Rebel best, both in texture and for the range of flavors. The Halo Tops I've tried have been good, but in my experience they melt down as quickly as the cheap house brand gallon bucket ice creams elsewhere in the freezer section. I'm not a huge fan of ice cream soup. I don't remember if I've tried the Aldi once or twice, but it didn't ring the bell for me -- the flavor was good but the grainy texture of the ice cream put me off.
As they sometimes say, though, sometimes the miracle is that it works at all.
