Noise reduction, weight, length and tone are objective measures to consider.
Don't rule out future use and compatibility with as many different hosts as possible.
I have an 30 cal Omega, 46 Hybrid, 30 Saker (Chimera now) and a 5.56 Saker.
Sakers are tanks. Heavy but great cans. Not at the top of my list though.
Omegas are just great. Great tone, incredible sound suppression on subs out of a 300 BLK and just works on everything 30 and under.
Now, I get to the 46 Hybrid M the hybrid M breaks down to make a smaller for pistol can for 45 ACP and under or for a lighter hunting can. This is a serious contender for a "one can" household.
Depending on your potential future use, this one could be a great choice. 223, 9 mm, 45. Any 300 anything up to to 338 Lapua, 45-70, 375 H&H as well.
It has the exact same end cap thread as the Omega, so, you can get a .30 cal endcap and make this a big 30 cal can. You can break it down to shorten it where it looks (and probably works) exactly like an Omega.
I'd look seriously at this if you have guns bigger than .30 you might want to buy and suppress.
