This is not something I am an expert on and like people say, depends on what you want and your expectations. My best between my Brocock, FX, and Taipan price vs. quality is the Taipan.
Honestly, I feel FX keeps a few things “out” to create a large aftermarket for the gun, i.e. for companies like Saber Tactical. The picatinny rail for the for mounting a bipod on the the Impact is a joke. The Impact should come from the factory longer / extended and not require you to spend $60 / $150 to buy a 3rd party part to increase stability. (Yeah I know there are different mounting systems, but still picatinny seems the “standard” for a majority of guns) AND the for example, the Crowns should come with at least an already mounted picatinny rail.
There is my soapbox speech.
