No. Wood stocks respond to glass/epoxy bedding better than most synthetics do. Most of the factory "synthetic" stocks are made of plastics that are not rigid, expand and contract as much or more than properly sealed wood, and are too slick for bedding compound to adhere properly.
The higher end fiberglass stocks with aluminum bedding blocks can and do outperform wood, but are expensive.
The cheap plastic OEM "synthetic" stocks are generally inferior to wood in nearly every respect. IMO, to outperform a properly bedded and sealed wood or laminate stock, you have to go with fiberglass stocks that incorporate an aluminum bedding block like Bell & Carlson, HS Precision, McMillan, or Manners.
A wood or laminate stock responds well to bedding. A flimsy plastic stock is best replaced with a better quality fiberglass stock. Bedding work is comparatively inexpensive.
