I'm not sure what specific case we're talking about here,
but in general, one uses generics (or templates) when
complete type information is available at compile time,
and tagged types when type information is available only
at run time.

Under typical compiler implementations, very large gains in
efficiency become possible using generics, mainly because of
inlining opportunities.

You may not like this, but the Ada designers clearly saw generics
as a benefit, and the C++ metaprogramming developers have sealed
its fate - generics are here to stay, and will probably become
more enhanced.
