Sorry but that is simply not clear at all.
Tacotime who is very experienced and respected in the community, has been involved with many coins, and is a very serious cryptocoin developer himself (MC2), is adamantly opposed to the ring signature trimming for example. The anonymity "improvements" have been strongly panned by the cryptonote developers. I don't think we have stated a position officially but we definitely have some issues with them as well, and definitely don't think they are the best way to "solve cryptonote flaws." The proof-of-work has plusses and minuses, but in reality both are somewhat questionable compared to something more of a hash-based standard. I happen to personally agree with you on emission curve, but others argue that it is better to reduce inflation a bit more quickly to achieve better store-of-value properties.
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
I would fully support BBR.
~BCX~
It will be great for crypto generally when you do.
XMR and BBR have a very friendly rivalry, though highly vocal and bitter foes spout off from each camp at the periphery.
The ring signature's prospects are new and developing. There is far more future than history in this, and thus, opportunity.
Especially for someone that values their privacy as you do.
XMR is sort of running away with the competition now, so it would be great to have a closer battle. More evolution from both.
You would likely be welcomed among XMR's noble opposition.
The endgame is possibly for these to ultimately join, or create a new joint effort coin, or something else, who knows?
As an admitted XMR fan, I put my support (and a bit of money) on that horse in this race, but I'd be foolish if I were not also owning BBR and saving up for what may yet come.
