For me the 5R is pefect. The stock fits me, I like the forend of the stock and the palm swell is perfect for my hands. It puts my trigger finger right in the perfect spot, which allows me to squeeze the trigger straight back. The trigger is heavy and feels about 5 pounds, but there is no travel, or creep and it breaks like glass.
Mine has shot .5 moa with Federal 168 grain match ammo. Below 1 moa with Fusion 165 grain hunting ammo. I plan on trying 167 Lapua next.
With my .5 moa. I pulled the fourth shot to the left. I should know better than to look at the target. If I didn't screw up that forth shot I would have had about .3 moa. This was off a sandbag for the front and a flat bean bag for the back. I'm a beginner at this.
From match off the shelf ammo, and a stock rifle. I can't complain. I'll get the trigger weight lowered and it should be perfect.
As has been said there are no guarantees. I've had rifles that should shoot fantastic groups and they haven't lived up to expectations. Plus if it doesn't fit you, then you'll never be comfortable.
As for cost. I don't consider the cost of these rifles to be all that high. You're getting an HS stock which free floats the barrel and has a bedding block (My personal favourite synthetic stock), Stainles action with Jewelled bolt, a 24 inch stainless steel barrel with 5R rifling and a 1/11.25 twist rate. I really do prefer the 24 inch barrel over the 26 inch. With a loss of only about 40 fps I find the handling, weight and look more than makes up for the velocity. Plus a shorter barrel may be more accurate. Overall it's a quality package that delivers fantastic results without the need to handload. IE anyone can go buy the ammo and be up and running.
For me this is currently my favourite rifle although I have a 7mm wildcat to get up and running

.
Also since the 5R is a limited production run it has some collectability to it. There is also a cult following to this rifle. Mine has lived up to that following.
