CO2 disposable bottle or CO2 reusable bottle? 
There are 2 different bottle types: Disposable cylinders, which are disposed of after emptying as well as recycled, and reusable cylinders, which can be refilled again and again. Refilling can be done by many pet stores and gas companies. If you live in a region where refilling is problematic, for example, the disposable bottle would be an alternative. Should the refill situation improve, you can always convert the disposable pressure reducer into a reusable pressure reducer in 2 minutes by screwing on the adapter (JBL PROFLORA CO2 ADAPT u-m). Aquarists who live on islands, for example, are sometimes not allowed to transport filled reusable bottles on ferries or planes. Disposable bottles are then sometimes allowed! 

The size of the bottle often depends on the cabinet in which the CO2 storage bottle is to be placed: A 500 g disposable bottle is only 31 cm high (plus pressure reducer = 37 cm), a 500 g reusable bottle with stand is already 43 cm and a 2000 g bottle 45.5 cm high. In principle, of course, a larger bottle is advantageous because it simply needs to be replaced or refilled less frequently. 

TÜV testing of CO2 cylinders: 
All reusable CO2 cylinders must be tested regularly, every 10 years, by the TÜV (at least in Germany). On the bottle you will always find, sometimes however poorly legible, the date of the last TÜV test and sometimes also the year of the next test.
