Eh. Sectoral bargaining is very very different from the much more-confrontational US model where individual firms unionize, to the extent that I don't really think they should even be in the same category as each other. In an alternate history sectorally bargained US, auto workers might actually have lower wages than UAW workers do today because the manufacturing industry sectoral union wants to have a more competitive export sector. They are just two completely different models of not just unionization but how to organize society and have labor-corporate-government relations, so it's not helpful to compare them
