The first few episodes (first entire season maybe) of Office US is worse, but as an entire series there’s little argument that the U.S. version was more engaging, created more diverse and memorable characters, and had much better storylines. Most of this is purely because it ran longer, but it’s really a very different type of show.

Absolutely agreed it's McDonald's against a good restaurant, sure one serves more customers but it's nowhere near the quality

The office US is broadly considered the better version. It certainly had a way bigger market success.
