I pin baste and use a hoop. I'm quite happy with the Q-snap 17x17 frame. You can adjust the back/front tension on one side, while leaving the other bits intact, whereas with the round hoops, you often can't. I would hate to use a frame I couldn't turn so I've never used a floor frame.. The puckering might be due to having different tension on your back fabric versus the front. Maybe you're stretching part of the fabric and not stretching other parts? Etc.
