Is Barkley + Higgins better or WalkerIII + Pickens?

Getting multiple offers from the same guy, I’m giving up Walker (or keeping him with Pickens headed my way), if I ship Walker, he keeps Pickens & I get Barkley + Higgins (we’re also swapping Hockenson for Kittle, which is think is about a wash, but he wants Hockenson bad apparently), and I need a decent wr, so my decision is:

Barkley + Higgins or Walker + Pickens
