Indeed - The Focusrite devices are great. Personally I do not like USB devices very much, because a lot of the cheaper ones have a high latency (and crackling and popping when you try to go lower), but the Focusrite ones are very decent. Make sure you have the latest generation tough, because the older(1.1) versions have some USB problems.
Personally I like firewire devices better. I still use an old MOTU Traveler (yes - first gen) with a TI interface under Windows 8.1, and it has a real low latency while it's rock steady. The MOTU interfaces are not the cheapest (although cheaper than RME), but have a real high quality. That said - This are, of course, my personal experiences.
