So when I searched the specifics, this is what I could find all of these seem to have good reputations and good followers, if the oil is not on this page, its overall ratings were below the overall average of the ones listed. That doesn't mean you are getting crap oil, just means that scientifically and on paper they are not as good.
Maxima Maxum - Specs are great - seems to be really good for clutch and older engines - highest in anti wear additives
Castrol - not recommended for older/classic/vintage
Mobil 1 - requires more frequent oil changes but is best for wet clutches - considered a "go to"
AMSoil - not really 100% synthetic - has more acid fighters/neutralizers for longer oil change intervals - reduced noise - hotter engines- no other real benefits
Lucas Oil - seems to be a crap shoot of whether or not your bike will "like" the oil - when it works, great reviews
Royal Purple - tons of zinc, really expensive, sucks in cold weather - reduces noise - bike specific
Motul - above average - bang for the buck - bike specific
Diesel (Rotella) - standard grade oil for diesel engines - more frequent oil changes, higher acid neutralizers, high additives for anti wear - not for high RPM's - cruisers 1000 mile oil changes
Red Line - Like amsoil - engine runs a little hotter than amsoil - makes claims of "highest levels" but is in the same ball park as all the other oils
BellRay - Not really any different than the others in any way. - average performance
Conclusion:
Groups:
High Heat:
1. Tie: AMSoil/Redline
3. Royal Purple
Everyday rider:
1. Maxima Maxum
2. Mobil 1
3. BellRay
4. Tie - Rotella/Motul/Castrol
In the end, the cost almost evens out for all of them. You are trading frequency of oil changes for longer oil life for additives for base for performance.... you can't have your cake and eat it too when it comes to oil. Boils down to personal preference... what do you prefer... there is a trade off for each one.
