I'd say the best bang for the buck would be MC semi-synth. It's price ranged to be nearly identical (and in many cases below) conventional oils at WM.
Naturally, if I ran across some really banging deal (like $0.49 after rebate) ..it would surely be tempting to take advantage of. I personally can't stand rebates ..but that's just me.
I share Quest's view, more or less. In common usage I just don't think it will make a difference. Now not all SM oils are created equal. They do have to meet the same thresholds of endurance ..but some can meet them better than others. Given the severity of the testing for certification, I'd still say that all of them do a great job.
