I bought an Orange Pi because it seemed a bit faster than the RPi3. Eventually I ended up buying a RPi3 as the Orange Pi didn't play well with a normal HDMI to VGA adapter (RetrOrangePi dev told me YMMV). Besides that issue, working with such a "clone" is just not the real experience. Shaders not working, certain wifi adapters not working, etc. You can try, but don't expect "support" when it doesn't work.
