I guess the LN is Lightning Node, which of the lightning nodes wallet is easier to grasp as a beginner either custodia or noncustodial??
Custodial is always the easy way to use since you only need to creating an account and it's ready to use.
While non custodial needs you to open a new channel, fund it etc that looks more technical.
But it we talk about security, non custodial is always secure than the custodial one. In custodial, you're relying on someone else channel, if the owner want to close the channel, you will lose your coins.
