It all depends on razor you use.
I have got Muhle R89 and feathers were better than astra, now i have got Muhle R41 and astra better suited to that razor than feathers.
Gillette and wilkinson imo very average and safe for newbies, but to be honest you have to understand preshave creams, your shaving soap, thickness of lather. Those little tricks will allow you to explore aggresive shaving which produces superb baby bum finish.
So Astra are very versatile and good value for money, Feathers if you perfect your preshave and lathering techniques, Derby are decent but not as smooth as Astra. I was very surprised by Arco stainless steel, cross between Astra and Feathers.
And get yourself an allum block bar, it will save you from your enthusiastic adventures in shaving world.
