So, for my 2 cents. Coiling Dragon is one of my favorite novels of all time. I like it much better than The Desolate Era. However, Coiling Dragon goes big too, I mean, it's IET. Also, CD has my favorite female love interest of the majority of the novels that I have read. Coiling Dragon is complete, so you don't have to worry about those almighty cliffs.
Library of Heaven's Path is also very good. As others have said, it is a light read. It is super fun, but you will have to face the cliff boss everyday while waiting for new chapters.
Warlock of Magus World is not everyone's cup of tea. It seems to be one of those novels where you either love it or hate it. The main character is different from your typical main character. He only looks out for himself and is a bit of a sociopath. Whatever benefits him is what he will do. This turns a lot of "righteous" people off of the novel.
As for Renegade Immortal, it's Er Gen. What's left to say?
I have not read MGA, so I cannot help you there.
