The issues raised by lipa in their post (that LDK is a complicated API and a lot to work with, that RGS had some stability issues, and that LDK’s pathfinding was sub-optimal) are things that were true a year ago, but are also things that have been largely addressed by LDK itself since -

The introduction of ldk-node has made it incredibly easy to get from zero to a full lightning node on a phone in minutes, RGS has seen a lot of debugging and improvements, and LDK’s pathfinding is now by far the most advanced in lightning (but, like with all lightning nodes, you need to be well connected or have sent a lot of payments to have data to use for pathfinding). nostr:note1zsmqhmny6q3zvrlqyfj7r2uu6wgrge8473d0vj95hmh98k98vj7qzga33w
