This is where the debate has another axis - when.
Quality matters, delivery speed matters, shipping also matters, where it matters and when it matters is much harder to get right. But it's also self correcting - if you don't, the project or business die - you can only get it wrong for so much or for so long.
To only discuss on one axis is presumably why GNU Hurd have never shipped or how claude-c-compiler doesn't compile hello world.
