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).
