There are things where you can't trust "the EU" (whatever this is supposed to be, the Parliament? The Commission? The countries?) and there are things where you can and absolutely should.
Generalizations are propaganda, and this is what you do here.
I'd never trust neither the commission nor the parliament. They have so many ridiculous failures under their wings, that nobody well-informed would. The best you can hope for with new legislation is that it's so vague and incomprehensible that in practice it's going to be unenforceable. But that's only so long as the judicial stays sane, which you can only hope for.
In addition EU is working hard to gain control of information flows at the moment. Censoring and cooperating with censors to block information providers in EU. All of this happens very discreetly and very silently. And I'd wager 95% of citizens are unaware that their right of free speech and information about events is being curtailed to degrees that is completely incompatible with a free society.
How you can even begin to trust a creation acting like this, is beyond my imagination.
The main difference between a law by most national parliaments and EU legislation is that the EU legislation is usually wildly more complex, oftentimes to the extent that nobody anywhere really can understand it. E.g. take a look at the GDPR or the EU electricity regulation. You will be getting wildly different answers to many questions, depending on who you ask. And the reason is clear: The regulation is unreadable and inconsistent.
On top of that, one would be thinking that EU should be painting legislation with broad clear strokes, for the national parliaments to implement the specifics. But they don't, often the EU commission goes down to a level of detail that you'd never even see in specific national legislation.
I can understand how lawyers see this monster as a great. It's an infinite source of income. But for the average citizen and cooperation, the good EU legislation would have been much better, had it been implemented by national parliaments. And much of the bad legislation would not have been possible in the national parliaments, where completely obscure nonsense usually is read by at least someone, that will call it out.

What's the problem with that?
In several countries, they even put up billboards next to projects they paid for.
