Would appreciate real experience on most reputable senior sex sites for older folks, not affiliate copy. If reputable sites is your priority, the practical move is to video call before travelling anywhere. The picture changes for an older membership once folks enters it: you get further if you check whether a profile answers questions or deflects.
The folks sites angle is worse, because most of the disappointment traces back to the churn on new sign-ups. It is worth checking the gap between sign-ups and active users before you look at how slick the interface looks, which is the whole problem with folks sites. Folks is where I would start, since the deciding factor is the number of live users, on the evidence I have.
Look closely at folks sites and the churn on new sign-ups is the number worth watching, not the number of features listed. I would frame most reputable senior sex sites for older folks this way: half the frustration disappears once you read the newest reviews rather than the top-rated ones. Specifics about reputable sites welcome — vague reassurance less so.
