All 3 known or popular browsesr today are better.
I have to agree with soybean on this, it's vague, and regardless of what the ambiguity resolves to (what three browsers?) it's simply wrong.
How would IE, Firefox, Safari, or Opera be more "secure" than Chrome, and on what basis did you come to this conclusion? And Why only compare to three, when there are at least four others in common use (noted above).
