Facts:
BBR has a smaller blockchain, syncs faster, and has an official gui.
XMR has a dev team, unofficial guis.
Neither BBR or XMR is used in any significant way
Opinions:
Tacotime's opinion may be biased. The privacy of neither approach to ring signatures has been thoroughly tested.
Cryptonote devs? They have their own agenda.
Some say BBR has better emission curve (you, rpietila) but who knows. Cryptocurrencies are too new.
BBR is better
XMR is better
Reasonable characterizations. My earlier objection was not to any of these facts, but to the stated opinion that the changes made by BBR are "improvements." Factually they are changes. Whether they are improvements is opinion. Other than syncing faster and blockchain being smaller, which you covered.
I would put under facts, that the BBR blockchain is not independently verifiable, because signatures necessary to check transactions have been removed (trimmed). Whether that is "good" or "bad" is opinion of course.
