What are the dogmatic gasoline "camps" we all fit into when it comes to our BMW E39

In a recent thread today, the typical age-old top-tier vs gas-is-gas discussion ensued:
- Shell v-power, by DominguesE30, in Australia

Some of this discussion is influenced by marketing efforts (i.e., "the big lie"), while others are influenced by knowledge of college-level inorganic and organic chemistry (most of us have probably taken both, including myself).

Predictably, just as in the motor oil & coolant camps, there appear to be a small number of differences of educated opinion on the age-old question of "which gasoline should I put in my BMW E39" which account for almost all the back-and-forth discussion.

It was harder to describe the religious camps for gasoline than it was for motor oil or for coolant, so, as is my habit, here is only my first stab at defining the dogmatic doctrines that already exist for what gas to use in a BMW E39 - we can correct the description as we move forward.

Is this a reasonable listing of the key camps we all fit into?
  1. Use only BMW-recommended "top-tier" gasolines with the recommended additive level & octane rating (it's on a list, or it's not)
  2. Use any gasoline of only the recommended octane rating or higher
  3. Use any gasoline of any common octane rating (i.e., 87AKI, 89AKI, & 92AKI in the USA)
What would you modify to better describe "our" gasoline selection decisions for the E39?
  1. Gas is gas only if it's top-tier gas!
  2. Gas is gas but octane is important
  3. Gas is gas and octane is overrated
