Should I use a bluetooth keyboard for iPad Pro or should I just use my Apple smart keyboard?

I recently purchased a Combrite CB-BK100 wireless bluetooth keyboard for my iPad Pro, and I also have my Apple smart keyboard for my iPad Pro, which now that I have a wireless bluetooth keyboard for my iPad Pro, I really only use my Apple smart keyboard as a stand for the iPad. But I’m confused, which one should I be using? Please reply to is post and any feedback from any of you would be greatly appreciated by me!!
