I have mainly used Ryanair for years now and always pay for a.checked bag, as l enjoy the freedom of just having my handbag with me whilst walking through the airport. The flight is only for a hour or two-year you don't need more than just your purse, phone and a tissue, if at all, during the flight In case of really dire emergencies, I do always have my toothbrush and some spare knickers in my handbag.
If you really must heave a case around the airport and onto the plane, there are umpteen specialists on YouTube with recommendations, some genuinely testing the bags and not sponsored by any manufacturer in particular.
