T05 is edgy, fiery, fast and hard to control in passive play. It has a high throw, and generates spin easily on active strokes. It's so reactive, though, that the ball shoots off fast if the serving brush touch isn't light enough. It spins very well.
T80 feels relatively dead on passive touches, but explodes on the scene when played actively. It blocks very well, and counterspins well too. Openups are bit harder.
This is all my €.02 ofc. Comparing the two, I'd go for — T19.
