What's your experience with metal bed frames?

I’m planning on purchasing a new bed frame and I came across these two that I really like (even more so because they’re within my budget). I’ve never owned a metal frame and I’m somewhat nervous about creaking noises.

If you’ve ever used a metal frame, did you like it? Was there ever any creaking? If so, what did you do to make it stop (other than replace the frame~)? Is creaking inevitable or are there any “preventive care” tactics that might help? Anything else you’d like to share about your experience with metal frames?
