Hi David,
You will find the differences in this page:
Cognos Analytics offeringsIt is quite strange to still have the 3rd tier because you can read the following in the documentation:
"In 11.2.0 and earlier versions, this offering has three tiers: Standard, Plus, and Premium. In 11.2.1, only Standard and Premium tiers are available for purchasing; however, the Plus tier is still supported for users who purchased it earlier."
Best regards,
