In production, is there a significant difference between QFN or TQFP components other than space?
I recommend QFN. why?


smaller, cheaper in mass production.
it requires less solder ( because of small pins ) and therefore monetary efficient.
it is soldered faster than TQFP ( using an soldering machine like that pick and place that uses solder paste and hot air) because QFT packages stick to pad because of their GND tab.
The board will look niftier and neater :) and also more professional.
