If the Hasbro black battle damage doesnt bother you, then go for the Hasbro one as it is cheaper. Everything else is indeed similar physical wise between the Takara to Hasbro version. Its mostly the paint apps where they differ (and price range) Hasbro's battle damage is black paint smudged here and there, while Takara has em less and changed to silvery making Screamer look cleaner and as already mentioned the nosecone has that decepticon sigil for the Takara one.
