Used to have buggy experience, mainly because of learning Lightning and self-owned node limitations. Had problems with:

-no payment routes (because of lack of channels to/from my node)

-too little liquidity, only small payments succeeded(because my channels were too small)

-bad connectivity when paying(because of congestion on Tor-network used to connect to node)

Have learned to fix those things, so they aren't much of a problem now. When you go custodial like ZBD, wallet of satoshi, ln.tips or the late LNTXbot on telegram, points above aren't your problem unless you pay an amateur Lightningnode like mine.

Lightings 'flaws' IMO:

-Ultimately limited by base layer, it only scales base layer a factor. High fees there means high costs in Lightning maintenance of channels

-Lighting nodes need to be on and reachable at all times for payments, this doesn't suit hardware used for Lighting like phones or Raspberry PiS (although there is lots of innovation and improvement done in this area)

-it's end form is still unclear and widespread adoption is still lagging. It could turn into a (corporate )settlement layer for payments between entities like ZBD and PayPal, or a pleb 2 pleb network of communities like El Salvadors BitcoinBeach and (Dutch) Satoshi Radio. Either way its still quite small communities and only a handful of companies that have yet adopted it.
