Both work and have advantages and disadvantages.

Personally, I like the fact that IPv4 and IPv6 control plane are 
different, thus I'd go for OSPv3. ISIS-MT means you have to know that all 
your ISIS speakers will handle the MT packets gracefully. I know products 
from large vendors in the market which do not (IPv6 not enabled, it 
receives IPv6 MT packets, affects IPv4 ISIS control plane badly).
