Weight would be the controlling factor to a large degree. Especially in the competition area where there are restrictions on weight.
Otherwise from both the appearance and ridgid standpoint, wood laminate is tough to beat.
As for accuracy alone, especially where weight isnt an issue, i feel some of the old school methods of barrel blocks, action extension sleeves, or one including the entire action is still a viable solution, especially in a glass or laminate stock.
Of coarse cost is usually a factor as well, especially where mass production is involved, as is the can i do it myself question.
