You get different degrees of inletting from Boyds and several other stock makers depending on model, type, and degree of finish prefered. Boyds is no better than some, and no worse than most of the ones I've seen. They all should be glass and pillar bedded. The cheaper plastic stocks are not worth the trouble of bedding. A laminate is the most stable of the wood stocks. I like the thumbhole on heavy recoiling rifles where the added weight is a plus. They are a little slower getting to a second shot till you get used to them. I have a Boyds thumbhole laminate on a Howa 308 heavy target rifle. It was not that well inletted and needed a bedding job to get the most out of it. I've had several Royal Arms laminates that were much better but still needed the bedding job. The laminates are not as appealing as nicely figured solid wood stock but they are much stronger and more stable, if sealed properly inside and out.
If you prefer the look of a moulded hunk of plastic, with parting lines, air pockets, and no particular character, that's fine if you that like that sort of rifle. You don't have to look very far to see that the low end of the plastic stocks are junk. When you get into the better McMillans with aluminum bedding blocks, your talking more money than most laminates. It's only been in the last 15 years that anyone wanted a plastic or synthetic stock.
