I'd argue that it is more accessible to everyone including developed nations. It only requires a standard technology freezer - like that you have in a residential home. COVID-19 has already cost the UK hundreds of billions, so being able to roll out a vaccine with minimum hassle and without needing specialist storage and training on its handling, is an absolutely enormous benefit.

Honestly I feel like this vaccine is going to leave the mRNA-based vaccines trailing in its wake in terms of global government adoption.

Moderna's vaccine can be stored in normal refrigerator (at 2 to 8 degrees Celsius) for 30 days. It also can be freezed for longer storage. [1]

However for developing world the prices becomes the issue, so you are probably right, this vaccine is cheaper and thus more available.
