Muun is a great tool that makes trade-offs to have quality UX. I personally don't mind using it as a way to navigate between on-chain and lightning ecosystems without needing to run a lightning node and manage channels.

While there may be valid criticism for how their workaround allows this it is definitely an accessible tool for someone to start their bitcoin journey. Obviously I won't recommend it for storing a large stack but it's another useful tool in the broader bitcoin ecosystem.
