To be fair, Falkens do seem to be well regarded as a slightly cheaper option. If you want to save a few quid, then I wouldn't slate you for it.
The difference between a good tyre and a very good tyre (GY, Vred, PS2) under normal conditions is marginal. However, the really cheap rubber can be lethal.
I'm sticking with the premium brands just for my own peace of mind.
