I'd also like them to provide some more useful insights to help with buying decisions. I.e. Don't just tell me you like it, I want to now if, for the money, I should buy this gun, the Daystate Huntsman or the BSA R10 mk2 etc.
For the money, buy the Streamline. The Streamline and the BSA will likely be as accurate as each other. The Huntsman, is going to be the sexiest gun of them all, bar none. Daystate seems to put a lot of their manufacturing effort into making what I would call "heirloom" guns that are incredibly good looking and certainly well made, but that seems to be at the expense of other attributes. For example, not being regulated the Huntsman will be the least efficient with air and will likely be less consistent, especially out at longer distances when you would have to pay extra attention to where you are in the power curve of the gun.
In my experience, the BSA and FX are basically on par with each other when it comes to accuracy. The BSA and FX are both regulated and have proven barrel technology. The FX has a little better trigger. Easier to adjust and can be adjusted lighter if desired. The FX also has the ability to adjust the power. Lastly, while the BSA is a cracking accurate gun, and I certainly don't want to part with mine any time soon, it has a fairly noisy hammer system that is exaggerated when you have your cheek on the stock and pull the trigger. In short it is a less friendly shot cycle. I depends on what you want most.
I'd say Daystate is the best looking with the least amenities, probably not the most accurate at distance without a regulator.
FX is the opposite, not the best looking, but has the most amenities. Regulated, very accurate, adjustable power.
BSA is in between. Pretty good looking, Regulated, very accurate, no adjustable power, slightly heavier trigger, and louder shot cycle.
