I think the latter version, branches_expr, would be faster, but only by a
merest sliver of a fraction. The external method is after all another stack
level. Using the branches expression skips a step. Compare

EM: branches -> external method -> tree-list-expression
Direct: branches_expr -> tree-list-expression
