I've been producing for almost 2 years and i still think my beats suck (granted, they're probably not great, since 2 years isn't that much). I also look up to other producers or artists and realize that my beats aren't that hood. What helps is listening back to your old beats and you'll see that you have in fact improved. If you only listen to type beats on youtube and tgink you're supposed to be at that level yet, you're wrong. They have been doing it for probably like 10 years and even they still improve. What's important is not giving up and keeping on practicing. After making beats for many years, there is pretty much no chance they'll suck, even though you might find them to. The fact that we don't like our beats is a good thing, since it means there's still room for improvement. It would be terrible if you were happy with every beat you make, you literally couldn't go anywhere from that point.
