Inditex (Zara) is a juggernaut compared with Gap or Primark. The differences in scale of operations, targeting, and branding are massive. It is like comparing AWS with Cloudera.
I find the rapid store expansion a problem and wouldn't be surprised if they repeat the same mistake, although they haven't plastered their clothes with Zara logos.
Uniqlo is the only store that hasn't yet repeated this mistake.
