The best Program for Map making

So i am making a version of Five Nights at Freddy’s 2 (Due to the cancelation of Those Nights at Fredbear’s and Unreal Shift at Freddy’s) And i’m trying to make the map in blender… let’s just say it got Freaking insane. And it got too much for me. So i was wondering… What is the best program to make the map in. I would use something like 3DS Max but with services like Netflix Hulu and other things we can’ afford that. But yeah. What is the best thing to use.
