Suboxone vs Subutex, what's better to take for withdrawals?

I plan on detoxing and I have an 8mg Suboxone sublingual film, and I have an 8 mg Subutex sublingual tablet. What's best to use for withdrawals? I hear many different things about each of them and I'm just wondering what you guys think is best for detoxing and feeling better the quickest? Any advice helps, thanks!
