Head-to-Head Comparisons
Three comparisons that end in the question deciding the choice rather than in a winner picked for someone else's patio: two pergola sizes, two roof types, and two grills.
Why these end in a rule
A comparison that names a winner is only useful to a reader whose situation matches the one the writer imagined. These end instead with the constraint that decides it, so the answer changes correctly when the patio does.
10×12 or 12×16 →
120 square feet against 192, curtains against pull-down screens. The difference is not more of the same - it is whether the furniture sits under the roof or inside a room.
Louvered Pergola or Gazebo →
One roof moves and closes to full shade; the other stays put and passes daylight through. The question is what you want the light to do.
Three Burners or Five →
36,000 BTU against 74,000, and a grill against three appliances in one frame. What the extra burners are actually for.
