The answer to your query is very subjective
It seems that some people that are very use to "edit and save" software have some problems coming to grips with its way of working.
While others (including me) find it very logical.
Once you understand the LR "approach" I think it becomes easy. Certainly easier, in my view, than PS.
LR does not completely replace PS but for me (and many others) I use PS type software very rarely.
