Those albums were done by Max Bedroom, not DOOM. They are DOOM beats though.
When you say his beats suck do you mean that you dislike the samples that he uses?
Not everyone can appreciate his rhymes or beats but those albums are a bad place to start regardless.
If you want peep his shit check out MF DOOM - Operation: DOOMsday! (mostly self-produced. You may not like the samples he uses but you can learn to appreciate the sound he creates with them.) or Viktor Vaughn (one of his aliases) - Vaudeville Villain (no DOOM beats).
If you end up disliking him there's nothing you can do about that but if you stop listening to him because for example you think his flow sucks, then you need to listen better. He slurs and this makes people think his flow sucks but they need q-tips.
