Take apart cans used to be not so common, but the market is demanding them. 22 rimfire is dirty and leaves lots of powder fouling. The major issue though is the lead buildup from the non-jacketed bullets which will eventually fill up the can.
Sealed cans are generally lighter, but can't be as easily cleaned.
Take apart cans are generally heavier, but can be easily cleaned and can easily have the baffle stack upgraded by an SOT down the road.
Centerfire rifle cans are generally sealed as the jacketed bullets don't leave lead fouling and the powder fouling is easily cleaned with solvent.
For a first time buyer, I would recommend you get a take apart can. Other than that, it depends on what you want. There are plenty of take apart cans to choose from. TacInc used to be the place to go for a first timer because their cans had the best performance for the dollar in a take-apart package. Now that is no longer the case as the number of choices is simply mind boggling.
Some people want a lightweight can and are willing to sacrifice some performance to get that. Some people want maximum suppression and are willing to have a heavier can. Some people want something that extremely Murphy resistant. Others want something that is full-auto rated. People who shoot their can on a rifle will want something different than someone who shoots their can on a handgun. The person who uses their can for both will want something else.
So you need to think about not only what you are getting now, but what you might get in the future.
