It's a static vs dynamic loading question.
The idea is in off-center hits, the face surfaces on a standard flat-face joint can come apart due to the lateral (transverse) force. That can create that ping. Most of today's modern cue makers do a pretty good job at their thread fits, so it's not as big of an "issue." In fact, it really isn't an issue at all for most people.
Both the Lambros and Schuler joints are designed to address this as does the Layani joint by designing in radial compression. The old school pilot joints (nubbin) did a decent job, too, but IMO the Lambros and Schuler joints are superior. Across most of the off center hits at most speeds, the vibration and sound at the joint feels pretty consistent in the Lambros and Schuler.
The downside that I've heard from feedback is that some find the Lambros and Schuler to be "too dead" or "too muted." Many people like more feedback from the joint hit. If that's what someone wants, I wouldn't suggest a Lambros.
To the original poster, you can't go wrong with either Webb or Lambros. Both are excellent cuemaker who put a ton of effort into their respective product.
