If you stick to recreational and non-urban areas, the A2 CofC doesn’t give you much advantage, but note that the Article 16 Operational Authorisation from FPVUK (and others) can only be used for sport/recreational purposes, and you can’t use automated modes on your drone under it - stick controls only.
There are also big advantages to the A2 CofC if you had a drone in the range 250-500g, but that’s not many people.
