i find the other two overlays to take up equally too much resources, chop frames, and be awkward to set up. the wmr overlay is literally one button and you have a desktop anywhere. 
however, the program compatibility with the other overlays is better. for example, wmr won't properly display winamp's classic layout (in fact mine just gives up trying to run winamp at all) but xsoverlay and ovrtoolkit do it just fine. 

it used to not be so convenient, i remember when i first got it you could not do the desktop windows while steamvr was running. now you can, and i get better performance in pancake mode games, in the basic steam holodeck, with a wmr desktop window open then i can achieve with virtual desktop or steam's own desktop viewer. not that i often play like that, but recently i was forced to use my computer without a screen and wmr's fairly complete integration with windows came in handy.
