I'm probably a bit of an outlier, but I do find it more readable to use type parameters instead of concrete types. If the type is opaque, I know the only ways to get or use values of that type are whatever explicit means the specifier of that type provides. This is less valuable the more specialized the type you're looking at -- generifying everything is just as much an antipattern as anything else -- but String is so widespread and abusable that it really is helpful to abstract over it in many circumstances.
