CasaOS vs Cosmos. Which one should I use?

I’ve been using CasaOS for several months now, and it’s been a reliable solution. However, recently I’ve been contemplating a switch to Cosmos.

Should I make the move to Cosmos? Additionally, is it possible to use a Samba Server on Cosmos?

Are there any potential disadvantages I should be aware of if I decide to switch to Cosmos?

Thanks in advance.
