For me it's whichever ones are closer to
The Rebirth...
So Hardhead, Skullcruncher and Weirdwolf -- Takara. (And likely Mindwipe.)
Will probably have to go with Hasbro for: Brainstorm (no mouth) Highbrow (brown head) and Chromedome (big visor-eyes.)
Unless of course I'll decide that this whole thing is getting out of hand and drop everything.
The extra vehicles that Takara is "making us" buy kind of put me off because of the price. (the yen has also been going up.)
You know what else I'd like to see in the "Legends" line though? A deluxe class cartoon-accurate Optimus Prime; a literal one, not just the deco. The old
deluxe was a nice action figure but it doesn't cut it anymore next to some of the new figures. Very unlikely, I know. Because this line is all about repaints and remolds of Hasbro releases.
