I'm not going to compare PI to ULA-C as the latter isn't well defined 
(no draft) - but - for the sake of seeing if I'm understanding the 

Comparing PI and to some addressing scheme that is purported to not 
be in the DFZ:

1) Both are the same amount of work and benefit to the RIRS.

2) PI puts a route into the DFZ, the other thing doesn't.

The latter point makes the non-routed address scheme less "costly" to 
network operations.  OTOH, as both are the same in the registration 
process I would think that they are the same under all other RIR 
policies (cost sharing, reporting, whois/in-addr, etc.)

At least this is what I have gathered from reading the threads on this.

Sarcasm doesn't scale.
