Oil flavor preferences are an emotional response and are useless until you get an oil analysis performed. An oil analysis, such as you would get from Blackstone labs, will tell you everything you would want to know about the oil in your engine. If you think 5000 mile oil changes are good enough, or if you drive so little you wonder if once a year is good, get a sample tested from your next two oil changes. Blackstone will tell you if you can go longer or not, AND they can tell you if your engine is wearing between changes.

Also, any oil company will tell you that their product is best...

 

This guy will not put one more drop of castrol edge in his mini. I burn more castrol than I do liqui moly. No blackstone analysis here, just real world experience. I’m under the hood enough, especially when heading to the Dragon, to know on these 2. I have finally got rid of the burnt oil smell from my last dragon run at the beginning of March, yes it was castrol edge.

 

I would certainly have used RL at least once if I wouldn't live in Europe, where RL uses to be much more costly compared to the US. RL is almost double the price of Ravenol REP over here, which comes with similar quality base oils and some fancy Vanderbilt W-324 add pack plus LL-04 approval. With this approval I can even take it to the dealer and have them perform the oil change. Keep in mind EU fuel is low sulphur, which translates to being fine with C3 (mid-SAPS) oils. LL-04 2018 is the more demanding spec compared to L-01 (which has been updated in 2018 also).
As stated earlier RL's new line of approved oils isn't the same quality as their traditional fully synthetic (PAO & POE based) oils. These oils are based on HC, similar to the vast majority of 'fake synthetic' stuff you can buy. I don't doubt they still perform sufficiently and most won't notice much if any of a difference. This begs the question, why paying more for RL over say Mobil 1 ESP?

 

I haven’t tried the new RL’s oils, but I did notice that they were less expensive than their other oils. If it is more cheaply made, then I would not bother trying it. I will also admit that RL is more expensive than what I care to pay, especially when I find the Motul to be almost as good in performance to my ear... Whereas, I find the Mobil 1 to be what I think is a lower quality. Again, I have no proof of this difference, just opinion. However, with track use the R56 cooks the oil. The ECU oil temperature reading hovers around 250 degF, which is really high. So I am concerned about what I use for oil and will spend the extra for what I think is good oil. With almost 70k miles on the car, this philosophy seems to be working for me.

As for the LL oils that BMW requires, when I looked at the LL spec in comparison to an otherwise comparable non-LL spec, I found no difference. Maybe I missed something, but if that is the case, then I would think that there no reason to use a LL spec oil if oil changes are going to be made every 5000 miles.

 

Please do not use this old oil!
Ship it to me and I'll test for free:

 

For what it is worth, here is a link to a BimmerWorld technical article about oils, including BMW spec oil requirements. It appears to be pretty definitive discussion about oils and summarizes the specs, requirements and explains the oil related acronyms.
