Well I agree with you for the most part except for the part about your pretty much stock VQ and using regular dino oil ... there is really no way for you to know if that dino oil is adequately protecting your engine from wear without doing a UOA.
Now of course if you follow the Oil Analysis thread, you should see several people that have had UOA's done on stock VQ's where you can see which oils have been shown to better protect your engine against wear.
What I'm saying is that 2 different dino oils of the same weight could protect your engine differently and that's why that Oil Analysis thread is priceless.
My opinion - don't just assume that the oil you're using is a good choice for your engine just because it drives well. Trace elements of iron, chromium, copper, lead, aluminium, silver & tin in your oil are the only real indicators of how well your oil is protecting the internals. If you don't do a UOA on your own oil, at the very least use the massive amount of information over at my350z to make an informed choice.

Synthetics, IMO, and really just IMO, is good for any manufacturer recommended applications where the oem oil is synthetic, forced induction cars, or anything where extreme driving conditions will be apparent. Custom built, and even factory cars, will come with engines built with different metals and metallurgical properties that will affect your oil use and its properties under different conditions, which will affect its ability to protect your engine. Iron blocks, aluminum blocks, iron/aluminum heads, chrome/moly pistons, rings, valves, springs, etc...the list goes on and on and on.
Well i hope to soon get an analysis on my oil for my stock VQ. For now, with my stock application, i'll stick with my dino oil stuff. But if i was anywhere nearly as modified as your car, i would have also looked into an analysis to see just how i can protect the internals of my engine with the best application available.
I had another cavalier, 1992 coupe, 4cyl. I drove it to the ground with 220,000 miles on it. all using different types of dino oil. was a good daily driver...my first car! :*(
