Disagree. While they can be fine, there’s a reason they’re cheap. Delays are more common than with flagship airlines and boarding/departing is often more grief (remote stands, small gates etc)
I’m currently flying every fortnight across Europe and in general have a better experience with flagship airlines compared to easyJet/Ryanair.
If you’re paying personally and infrequently then fine. But if the price differential is small and/or you fly a lot then a bit of a better experience and being on time means a lot
