O2 sensors brand recommendations?

[Susieq007]

I have a 2006 X3 3.0 and need to replace the pre cat O2 sensors. Im new to the X3 (previously owned '86 325es). What brand do you guys recommend? I almost always used Bosch parts on my old bimmer. Should i do the same here or are cheaper ones just as good? Just curious.
