None of them is better than the other. This can be a two fold process for 
LIR and RIR.

1. The network operator submit an application with DETAILED plan of IPv6 usage.
2. RIR/LIR evaluate it. They might want the applicants justify their IPv6 
address usage plan. They want the applicants to redesign their IPv6 plan. 
It can be subjective, but here LIR/RIR can be liberal.
3. Applicant get the address space.
4. RIR/LIR do an audit on IPv6 usage. Not only the address space, but real 
usage. RIR/LIR should compare the plan submitted in the application with 
the reality. This can be Draconian.

Any IPv6 usage is IPv6 address usage even a /64. You should not count by 
percentage, but you should count by number of routing entries. This will be 
the most constraining element... You should count the routing entries in 
your level, and one level of above you.
