It’s too new for there to truly be “veterans” however the hard product is very good. 787s obviously are great comfortwise with high humidity and low cabin altitude. You can’t compare the soft product to non-LCCs. But as long as you know what to expect and account for your addon expenses accordingly it is a great way to make the trip. My family flew the reverse last fall in econ and we’re happy with it. Plenty of YouTube vids showing you the food options etc.
