As someone else said, an instrumentation op-amp is a different beast-
here is one common configuration:

Usually so-called precision op-amps have unusually good *DC* characteristics
such as Vos (guaranteed maximum offset voltage), TcVos (guaranteed maximum
offset voltage change with temperature) and op-loop gain (minimum).
The AC characteristics such as GBW product and so on may be good or not.
