I used to think that, and I changed my mind. The fancy retrofit fixtures are almost universally flood lights where the diffuser is close enough to the ceiling plane that it’s visible from far off axis. The result is that the lights on the far side of the room cause unpleasant glare.
With a retrofit lamp, you can use a high quality trim baffle (these things cost about $12, are quite well designed, and are probably already in your house and put a civilized PAR30 or PAR38 LED in, and you get a much better light distribution.
Back when lamps were all standardized incandescents, fixtures could focus on quality. Now, with LEDs, I suspect that manufacturers focus on how cheaply they can build a driver and assembly that meets some minimum performance criteria. So, with retrofit lamps, at least the fixture design is separate.
(There are exceptions, of course. Very high quality dedicated fixtures exist, but they’re quite expensive.)
