Yes, they're all pretty much the same except for threaded vs quick connect. Some people prefer the ones with steel braided hoses for safety. The main "danger" of overfilling is that once the ice melts to liquid and boils to gas the pressure will go to the moon and burst the safety valve (permanently), becoming a broken tank with a small leak that vents gas quicker than the liquid can boil. Large amounts of rapidly venting CO2 create thick fog rolling along the ground (as seen in many halloween displays for example) so the leak would be obvious and is not dangerous as long as you don't lay down and stick your face in it and try to breathe for awhile. If you don't notice it you may be surprised to find your tank is empty when you go to use it, and any attempts to refill it will immediately start leaking. Anyway, it's an expensive mistake so you probably won't make it more than once. Technically the burst disc can be replaced, but that's beyond the scope of this discussion.

It's easy to avoid as long as you understand that filling can only be done reliably by weight, not by time, feel, eyeball or pressure or anything else. Whether you're using dry ice or liquid from another tank, the weight of the tank is all that matters. An empty tank is a particular weight which can be measured as it will have to be completely empty before you attempt refilling it anyway. A full tank is a higher weight. The weight you should not exceed should be printed on all tanks but for Sodastream-size tanks can hold exactly 410g above empty weight. Less is fine. More is risky (some people do exceed it regularly though, but that's on them and their wallet) Pressure is mostly meaningless for a liquified gas like CO2, the liquid phase maintains constant pressure as dictated by temperature and physics.

Liquified gases don't really "explode" like pressurized gases, they either vent, or leak. This can be noisy and visually dramatic but is not a safety concern. Even a catastrophic failure will remain mostly liquid for a long time and is just a spill of increasingly cold liquid that is creating fog (more and more slowly as it uses up all the available heat by becoming cold). The gas doesn't appear instantly, the liquid has to boil to make more gas, and that takes a lot of time and heat it has to absorb first before it can do that. The biggest risk is frostbite, not explosion. The liquid CO2 gets very cold when boiling freely, because of all the surrounding heat it's absorbing to try to turn into gas. It is not a fast process. This is also how dry ice works, and why it stays ice for so long, and why we can use it to make things very cold for a very long time. FWIW propane is also a liquified gas, and behaves mostly the same way, except that it is flammable, which can make it explosive under certain conditions. Some people are bothered having a propane tank next to their house, but most people aren't. CO2 isn't flammable or explosive, it's safe enough to have in your kitchen in my opinion. In a pinch it can double as a fire extinguisher. :P
