I’ve become a recent fan of TwinMotion, you can get some excellent results out of it with some patience. As a long time user of Vray (and still am) it is extremely useful to get a number of a images and animations out quickly. TwinMotion images certainly have a ‘look’ as all render engines do in their own way, and that can get a little annoying at times but I have only ever had positive responses to images.
Although as @JustinTSE said, there is no current support for displacement maps (and TBH I am not sure it will until Nanite gets rolled into the Unreal Engine version it relies on and then we wont need them anyway 
) there are Parallax Occlusion Maps on the roadmap that will help things for animation but for now, we have what we have and TwinMotion’s use of Normal Maps are actually pretty good as mostly for Archviz, geometry profiles can be occluded with the clever use of shadowing, vegetation and scene dressing.
Here is an example from a couple weeks ago, everything on the flat surfaces are derived from texture maps and normals, from the timber cladding to the stacked stone wall in the foreground, its not perfect but it does its communication job as this is just a ‘value add’ image for a project.
