The grammar/spelling stuff is all in good fun. I appreciate the audio guys input on the forums, as they have helped me debug multiple issues.

Back to the topic, here is what I've found, which is in no way comprehensive. I purchased my boat used, and it had all Exile when I bought it, so I haven't had to make this decision yet.

Pros/Cons of the XM9:
- I'm not an audiophile, but to my ear they sound great, and one pair is louder than I'll ever need.
- As mentioned, the customer service is fantastic, as I'm sure WetSounds service is as well.
- I agree with the comments about the guitar style connector. I'm not a fan. It's convenient to attach/remove the speaker, but I've had issues with the connection that the guitar style makes. I occasionally have to rattle the speaker around a little.

WS420 vs. ZLD:
- I've owned both, and for pure functionality, you can't beat the WS420.
- I find that when the boat is underway, the WS420 is harder for me to manipulate, especially the outer rings. The rubber coating on mine also eventually degraded. I'm not sure if the newer version still have a rubber coating on the knobs, but mine all started tearing off, which I found annoying.
- If I had to choose again, I would still choose the WS420. It just does everything you need, and the mic is also awesome.
