Bosch Professional GSR 12V-15 FC vs GSR 12V-35 FC brushless

Simple comparison of this two 12V screwdriver/drill.
GSR 12V-35 FC is louder with high pitch, have bigger but brushless motor, that generate more wind, but no sparks, have higher rpm speed (Speed 1 - 460 vs 400, speed 2 - 1750 vs 1300), higher torque (35Nm vs 30Nm, in hand you feel more movement after power on). Body is 10mm shorter (122mm vs 132mm). Light is not so bright, but is softer and not so disturbing. Magnet is weaker, weight i lower (574g vs 648g). Internals are not compatible, but FlexiClick head (locking mechanism, bit holder with magnet and bearing) can be mixed, so, if you need stronger magnet in bit holder (for using without FlexiClick bitholder head), you can change it (is possible to buy it as spare part from older model).
For test purpose video was captured on GoPro Hero 10 Black and it is not so good, as from iPhone 15 Pro, but, GoPro have other advantage and it is primary action cam.

Seems like quite a bit of lag between pressing the trigger and it spinning. Wish you would have tested for trigger granularity (very fine low to high speed).

Weight? Handle thickness? Thanks!

Weight is in description. Handle can't tell, but I mean, it was same because of battery size, that is same.
