Manual safety vs Decocker ???

[Guardian angel]

Hi everybody,


I'm in plan to purchase a CZ SP-01 soon.
My question is : for Production Division shooting, is it better to choose the Manual safety Version or the Decocker (tactical) ???
The decoker permit to reduce a little bit the trigger pull in DA but it seems most users prefer the safety version, I don't understand really why ? Maybe just a question of habit ?

(The Shadow seems to be not available in Belgium).

Thanks for replies.
