I wouldn’t recommend it to someone who hasn’t seen Star Wars before, but personally I’d go
RO
SW
ESB
ROTJ
TFAI think chronological works just fine as long as you leave the prequels out.
This isn’t a bad order, but I feel like RO is superfluous to the story. You get all the backstory you need in SW, and by cutting out RO it remains more tonally consistent.
That said, I think a modern Machete Order would be something like this:
RO
SW
ESB
AOTC
ROTS
ROTJ
TFA
Not that I would ever want to watch it this way, but it’s certainly an option.
