Let's be honest ... and use the tools for what they are intended to do ...
I couldn't try Alain's suggestions up to now; don't have any Schottky diodes neither 1nF capacitors... will be bought and tested by tomorrow evening.

My initial question was more about to understand the difference between both transistors since nothing else changes in the circuit.
This is exactly the same feature : junction capacities to discharge ... a strong cut off is obtained by polarizing the base to - 2 to 3 volts ...
just look at old "logic" schemes !!!
I wish this was true: I would bother you All again with a
methane powered PIC project
Ah, la vache !!! ...
have a Good evening ...
