One difference is that some sites (not looking at you at all, ALCF) still run pretty ancient drivers and/or have broken GPU-aware MPI with all but a specific ancient version of CUDA (OLCF, LLNL). With a normal compiler, you can choose to use the latest version, but with CUDA, people are firmly stuck on old versions.
