yes, it needs more time to learn, and requires deeper knowledge of C++, but there are also some higher level functions to be used for certain purposes e.g. character control, like in Unity, and those can be modified or expanded. so after creating your own system it could be more flexible.
at the moment lite-c is perfect for me, I have my editor what I control in 100%, so don't want to give up my developments without finishing them. but in future Esenthel can be a good option for me because it features a lot of things I need or I will need. of course, it depends on what 3DGS engine development provides in future.
