I've been really disappointed with MOOG quality over the years. It really is all over the place. I've actually had better success with their economy Quick Steer line. As for having a zerk fitting, it depends on how religious you are about greasing them. Most people are not car people so I prefer the sealed stuff. Also comes down to the application. Sealed joints usually use nylon bushings and fine for daily driver. But on a 2500HD work truck, that's where a metal bushing and greaseable joint makes more sense. And a lifetime warranty is really a gimmick. Who has the time to leave their car on jack stands while you're waiting on an RMA process. Just like with a tire warranty, would cost more to ship it yourself than what's it's worth. Putting that label on a box cost nothing, especially when they know no one is gong to bother with it.
