Pregnancy test accuracy

Has anyone found that the cassette pregnancy tests (the ones with the little circle area that you drop 3 drops of urine in) are not as accurate or sensitive as midstream or dip pregnancy tests?

I remember doing a cassette one with my first child and it was super faint, when I tested with a clearblue one the next morning it showed I was 2-3 weeks already.

Tested yesterday with a midstream test and I very clearly see a faint line! But tested this morning with a cassette test and it's negative.. Just wondering if it's just the tests? Testing with midstream again tomorrow
