OK.
I have used a few different ones, starting with CMMG (I think) way back when. Then some Aero, JP, WMD and Strike. I will always order without grip/trigger, since I will never want to use the defaults that come with the kits. They all work. Some are nicer than others.
Sooner or later, you might find yourself needed trigger anti-walk pins/sets.
You always want more springs than you need, and extra, when you start launching stuff by accident during assembly. Oh, and For Fucks Sake, always get extra c-clips for the dust cover rods.
