Well for the price , the indie version is really good, so i bought it.
What i like a lot : -I can import easily Blender models (FBX export) -When you select an object on the editor or hierarchy you have a small 3D preview window in the left panel and you can see all attribuets : textures, material properties, shaders in the panel. -You can make a terrain in some minutes (paint and sculpt) -Free assets that you have access , are really pro quality -Lot of things are visually displayed : sounds, collisions etc ...
Unity is incredibly good on the workflow point.
In A7 lot of tweaks , and things must be done by code. Even having to use two tools (MED abd WEDp) is painfull : MED and WED In Unity you have only one editor. You can import some FBX models, assign textures , shaders by mouse directly in the main editor
I like my A7 also , and i hope a lot Conitec for A8 will follow same workflow and let down the old interface.
