If the Wii U had full support from all the major 3rd parties, would it have competed with the PS4?

A lot of times I hear people say that the main weakness Nintendo needs to address with their console is the lack of 3rd party support. Hypethetically speaking, if the Wii U did have all the major 3rd party games would it manage to compete with the other two and taken away a chunk of their crowd? This despite the fact that the Wii U is clearly weaker hardware wise.

If Wii U still wouldn't have sold well without 3rd party support, is the issue that they make weak hardware? But then the GC and N64 had powerful hardware.
