Coming in a bit late also Kyurem is lacking a good part of Kyu Bs game in Teravolt, since Teravolt lets me do crap like Earth power a Rotom Heat. But yeah basically the same mon without its good ability, its lack of fusion bolt (which sucks considering it doesn't have Bolt Beam coverage) and that sweet sweet 40 extra attackKyurem-B (both types) S -> UR: Self explanitory
Kyurem (Dragon/Ice) D -> B: pretty much necessitated because of the ban, regular Kyurem's coverage is still good and its wallbreaking is still great enough to where this is the best possible substitute; they're the same mon p much besides the extra 40 attack and lack of Fusion Bolt.
Also i feel Kyurem norm is less easy to run mix sets and stuff. I think you have to go more or less all or nothing into one side of its reprotre aka physical or special... and in 90% of cases most people do specs special attacking Kyurem, though i guess a sub DD Kyurem could work.... just not as well as normal Kyurem
