As mentioned above, oils today are much better than oils of the past. Any modern SN/SN+ changed on a regular basis will not have an oil related issue.
When I joined here, SM was just being introduced, with many new vehicles still only recommending SH or better oils.
German Castrol (the Green Elixer) was all the rage here.
I was primarily a VWB user when I came here, no real reason in particular, maybe marketing? Over time, I just starting finding that oil deals were more important than particular brand.
Although I have quite a stash to go through, if I ever need to go buy some oil full price, Supertech oil (even their conventional) would be on the top of my list. When I got my motorcycle, I had no oil for it, so I bought a jug of Supertech 15w-40. I have since obtained a stash of cheap 15w-40 oil (Peak Syn Blend and Rotella T6), but again, was not buying based on any specific formulation or brand.
