TW can deliver well, but you have to manage them closely.

So closely you might as well just have hired a bunch of contractors and run the project yourself for a fraction of the price?

Not really. The TW devs are mostly guaranteed to be competent without interviews. They also already know how to work together, have a shared idea of tools, methodology, lingo, etc. The "manage closely" part is around watching for people swapouts, architecture shortcuts, etc. That's managing their managers/architects vs the entire team.
