It's really hard to tell until you walked in the actual done unit. Really depends on your luck.
We can't judge the judge the project quality base on developers.

As each project they might appoint different contractors, so the project good or not, defect much or not, it depends on the contractors.
Even the contractors are good, they have sub-contractors some more... Unless you really have someone work on the project, and know the profile of contractors then
you will have more accurate information.

But of course, the reputation of developers are important as if you found any defects, how fast is their response.
Just my point of view
