I sampled both in the shop and went for the 20'' blued fluted barrel. I prefered the shorter barrel as I was putting a T8 moderator on it so it still ended up quite long. I also thought that the blued barrel looked a lot better than the stainless one and I also went for the black stock. In my opinion it is a lovely looking rifle. It did add a bit of weight by the time the moderator, scope and bipod were coupled with the fluted barrel but it is still not bad.
Mine fires 100 grain RWS or Federal power shock rounds exactly the same achieving sub 0.5'' groups no problem. That is the rifle straight out the box no modifications at all, just zeroed the scope.
I can't fault it for the money.
Good luck with what ever you opt for.
