Ngk have been pretty reliable motor craft is pretty good too but I've seen good life spans for both.
Very broadly, only use NGK, Denso, Bosch, or Champion.
according to my halfords e- receipt i last used cr8 iridium plugs, no complaints here.
NGK all day, compared to all others they’re just made better, I bought Bosch platinum for a VW and the OE came out were NGK, after 50k they were still visually a better manufactured plug. Example- the plating on the Bosch threads was rougher.
Over the last 16 years with my 8 gas engine VWs and Audis, the OEM or OEM equivalent (Bosch or NGK) at stock gap (unless chipped) have performed better and more consistent than any other I've tried.
The NGK's have been a solid go to for me and my little Pocket Ferrari for every day driving.
NGK run good for me
Since I've owned my 18 S4 i've done almost everything myself:
4 oil changes, spark plugs at 40k, 2 sets of pads and 1 set of rotors, both air filters.
NGK and Bosch are the same ones as the Genuine BMW ones. The latter are just rebranded and marked up.
Replaced the plugs -- BKR8EIX per the hstuning blog. I'm still getting the misfires...
