I chose control. Destroy made no sense due to allying with the Geth and the Qunari, not to mention your robot companion, but also, it seemed as silly as the merge option - both seemed to be 'magic', unreal, whereas the control option seemed at least possible.
People only say the destroy ending was the best because Shepard seems to live at the end. But, for me, the beginning and entire content of ME3 said 'Shepard dies': it feels odd for him/her to live.
And I think this is ultimately why the game is so polarising: some people saw the game as being a chance for Shepard to finally 'win', whereas I and others expected (and got) a bittersweet ending.
