Depends on the model I guess. On my 1/48 FB-111A, I photoetched the hell out of that cockpit. On the 1/32 F-16CJ I'm currently focused on, I think photoetch would have looked a lot worse than the Tamiya kit parts because it would have taken all the depth out of everything. For that, I airbrushed/hand painted the kit details and added instrument decals. I did use photoetched seatbelts though in the F-16, because they look so awesome.
