Compare Planning Poker and T-Shirt Sizing for Your Next Sprint

Your team is about to estimate a backlog and someone suggests Planning Poker while someone else wants T-shirt sizing, and the meeting is about to become a meeting about meetings. This lays both methods out side by side: how they run, what they are good at, and which one actually suits a team like yours.
