Key-mo vs Xeno muzzle devices

[AEI_Own_U]

I have read that xeno is lighter, better, etc., and Key-mo is heavier, longer, but more idiot-proof and quicker. Is this weight actually noticeable? My rifle ended up coming stock with a Keymo muzzle break, and I am wondering if it is worth just switching everything to xeno before I get too far into it? Also, why is the xeno so much cheaper if its that much better? - could be obvious answer that its smaller so less material, but JW. Thanks for the help.
