Which?'s survey is not scientifically based is it? Aren't all members simply asked for their views?
Not all people of advancing years are wrapped up in the past when it comes to comparing lowcost airlines with legacy carriers of yesteryear. Many of us realise and accept that life moves on, and I'm very grateful for being able to fly to numerous destinations from my local airport which was not the case when legacy airlines prevailed.
I use easyJet and Ryanair and would not hesitate to use either again and will do so.
