Hi, Andi. Nice to see you back. I can't tell you a thing about the Oso Easy roses because I've never grown any. In fact, I don't think I've ever seen any. My local nurseries don't carry them.
I'm not thrilled with the drift roses. I have Pink Drift, Apricot Drift, and Peach Drift, and they're just like minis in my garden, not like groundcover roses at all. I've had them for years and they still form a small mound, not exceeding 12 inches in width. Maybe they need a cooler climate to behave like groundcover roses.
The best groundcover rose I have is Red Ribbons. It's only about 2 feet tall and spreads out to about 5 feet.
