The 4” backsplash made of counter material is a classic, practical, economical choice, but I generally prefer tile.

Are you talking about a full height backsplash of counter material? This is an increasingly popular choice, whether you are using solid surface, quartz, stone, or laminate. The biggest “con” is that it can look a little monolithic. The biggest “pros“ are no grout lines on the backsplash, and a uniformity of look. Google some images, and see what you think of the look with the material you are considering.
