It seems as though you could talk about a "better" thermal insulator
or conductor - without much ambiguity or loss of scientific rigor.

In biology, "better" would make reasonable sense - if the environment
was specified - though it would not necessarily obey the transitive
rule [i.e. http://mathworld.wolfram.com/Transitive.html].
