Serious - and I know NF owners are proud of their scopes smile

Owners of the VX-3 with CDS and/or M1s -

1. Any tracking issues?
2. Failures of any kind?

I ask this as it was long awaited for NF fans to have a 42mm version in this zoom range, I see Pros/Cons.

Con on the NF I see:
Price, weight, and reviews of less than expected glass quality.

I know the NF has a bullet proof reputation, but sell me on the value of a NF for 3x the price of a VX-3.

Looking for fact based info from experienced owners, not looking to pick an argument, just have a logic based discussion. Thanks in advance.
