Most pure gliders without appropriate field went electric. I'd say staying pure glider is great if you have enough energy and time to stay on-course.
It's just easier to fly electric on a small field and you always have a "second chance" on landing. Much easier to co-exist with power planes. Many benefits for electric.
Back in 70's and 80's there was no choice and we all flew pure gliders, just as in 18-th century most people used horses for transportation. Should we all give-up cars and ride horses again?
When we had no computers we used paper, pencil and a strange thing called brain. Not too many people get back to use those either
, so it seems.
We all here but we moved along and switched to a new thing.
