Generally no, you're far more likely to get something that DOESN'T do what's asvertised in my experience.
You can almost always tell the second it's in your hand; in order to do the high throughput stuff, 20Gb, 40Gb etc, the wire is much thicker and stiffer, it needs conductors for all of those contacts. Ive never counted but it's something like 20 of them vs 4 in a standard cable.
Of course always C to C; the A connectors with the extra contacts in between the normal USB 2 ones still aren't enough.
