Making a quad and using it for rotations is definitely slower than using good math ( optimized with sin/cos arrays ) on vertices.
Tform commands are also ( some of them much ) slower than plain math coded for particular case.
Believe me, I have spent a LOT of hours on finding fastest ways for dealing with single surface/quad systems.
