MAC. MAC = awesome quality.
MAC brushes are better quality.
MAC brushes are amazing.
go for MAC.
Probably the MAC one.
You can’t really apply foundation or contour with the 165 and the 109 would be the best for foundation. You can also contour with the 109 brush. If I were you, I would get 2 different brushes. I would get the 109 for foundation and the 168 for contouring.
Good Luck! =)
