I have never used lightning network, because so far I didn't feel the need for it, and because I was too lazy to learn how to use it. If the network is too centralised, it's a serious risk, but the fees people are talking about are amazing, and perhaps the former issue would solve itself if more people joined the network.
Bitcoin might be getting bullish again, and the fees are rising. If they get as high as they did in 2017, I'll give the lightning network a try. And others probably will too, since it seems to tackle the scalability issue better than anything else offered so far.
