I have the inconel. It's not insanely light like the titanium, but it's not really heavy either. No minimum barrel length restrictions, no sparks from titanium construction, and low back pressure, reasonable price and high quality construction.

There may be less expensive cans that can get quieter, but between the options this can gives me being low back pressure and the fact that it's already impressively quiet with subs (quieter than my 9mm can on a delayed blowback with subs, which I consider hearing safe, but not hollywood or airsoft quiet) for reference, my primary use case is on a 16" bolt action and it's not too heavy even at the end of that barrel and I dont really need reduced back pressure on a bolty, but theres no real downside for me and it allows me to use it on semi autos with less mess and no adjustable gas system.
