#1: How does this compare in price, parts lib, features etc to JLC? Obviously the price and parts avail will be a challenge.

#2: Is this accessible for hobbyists, prototypes, small companies etc, or is it a service for gov/mil stuff that isn't allowed to use China? (Blue UAS etc)

I'm excited and would love to order a board.

#1 price is more expensive than China, parts availability is higher.

#2 it is accessible, but more expensive so if cost is your main constraint it's not the right choice.
