Might be grave digging a bit here (by a month and a little bit or so) But I'd have to say that JoltFun, BitRefill, some random gambling websites (LightingSpin, etc) are going to be the best that you're going to find in the LN.
We have to first focus, as a community, on getting people into bitcoin usage first not into LN. It's not there yet, and we'd be doing them a disservice to push them into something that isn't ready and isn't really fully possible to use without bugs.
I'd love to see Bitcoin used at my local stores, that'd be great. But lets first get them onto something that works, not something that doesn't.
That's certainly true, mate. We should encourage people to use Bitcoin first, in order to drive adoption for the Lightning Network. While I'm quite fond with the LN's instant transaction speeds, and extremely low fees, it's not meant to be used as a replacement for mainstream BTC transactions. Even if people decide to use the LN instead of Bitcoin itself, they still need to own some on-chain BTC in order to open/close a channel.
Instant transactions prove to be extremely convenient for mobile payments on the go. With a variety of LN wallets for mobile devices, people are able to pay for goods & services in a seamless way. I'd have to say that the number of businesses/stores accepting LN payments are still limited these days. But at least, it's better something than nothing.
My most favorite LN services are Bitrefill, and JoltFun. I can buy gift cards online instantly with the LN using Bitrefill, while I can buy games online instantly with JoltFun. Sometimes I'd wish we had a sort of marketplace like eBay or Amazon that would accept LN payments for convenience. Maybe as LN adoption grows over time, we'll be able to experience this?
Nonetheless, I have to agree that the LN is still NOT ready yet for mainstream use. I know many people are excited about how the LN settles transactions instantly at a fraction of the cost, but there are still many issues that need to be addressed in order to make the LN a robust Layer-Two solution for micropayments. It's no doubt that developers are still working hard on improving the Lightning Network. Soon, we'll be able to enjoy atomic swaps, submarine swaps, and even Watchtowers within the Lightning Network. With all that's coming, I believe that Bitcoin will become much more attractive to merchants/businesses than any other cryptocurrency known to date. Just my thoughts
