Blender is great, but I find one problem with it.
I’m programmer who mostly codes or uses blueprints but sometimes needs to adjust some 3rd party models (like imported from Mixamo Fuse etc.).
Now the problem is that if you are using Blender rarely (a few times in a month or so), you forget many of its shortcuts and have to relearn stuff. Yeah, shortcuts are faster than clicking with your mouse, but only when you use them at least daily. For occasional users it is more important to have lots of buttons and toolbars with clear tooltips, and with a workflow which tries to adjust to standard software as much as possible. For example, I expect to select things with left mouse button, I expect Ctrl+Wheel to zoom and right mouse button to open a context menu for currently selected object. If 3D software differs from those daily habits, it slows down occasional users.
Sometimes I find myself banging my head against the wall thinking “oh, a week ago I was able to export this model from Blender to FBX and get it to work in UE4, but now I cannot. I vaguely remember that there was some setting or checkbox I needed to use, but I don’t remember exactly what it was, so now I have to spend some time browsing the forums or looking in my old notes to see if I haven’t written something down…”. Isn’t that a familiar feeling for occasional Blender->UE4 users? 
The 3d cursor in Blender also is sometimes frustrating - I often find that I have messed things up because I forgot that my model is affected by the position of the 3d cursor. So I have to undo some centering things I have done wrong.
Ideally, there should be a button “Just make it work in UE4 exactly as it works inside this 3D application”… Maybe Epic should develop their own 3D design software based on UE4 and meant for creating content for UE4, including modeling, animation, sculpting… ok, I’m just dreaming, I doubt that export of rigged&animated model with textures might be that easy. But hope never dies
So, I’m still looking for a all-in-one package and as UE4 compatible as possible, but also which has intuitive UI, so I don’t have to relearn all the shortcuts again and again. I agree even to pay some money, but not more than 100 USD because I need something which supports just the bare minimum to design characters and models for UE4, including animations, LOD levels and all the other stuff, but nothing more fancy.
I even looked at Maya LT, but Autodesk reports “This product is not available in your country”. Yeah, Autodesk doesn’t like my small country, Latvia, somwehere in the Eastern Europe…
