RPG Maker isn't really for pros.
You should never factor in ease of use into RPG Makers. They may differ between themselves but on the scale of game development tools, they are all very simple. If you think any of them is difficult to use now, just put in the hours. This should not be a factor if your choice is between only RPG Makers.
I would advise you to go with MV. It's the latest, is portable (eg mobile, html5 etc) and is built on Javascript instead of Ruby. Because of the way javascript works, you can use a console to assist you with programming which makes things a hundred times quicker and easier. For example, you can use the console to inspect a javascript object i.e. the game player is an object with various properties which come default code. You could spend hours reading the code (and you will anyway if you want to script), but you can use the console to quickly see the player's (or any other object at all) current properties, and methods/functions. TL;DR coding easier. MV. DL it.
