Depends what you wanna do with it. Two very different beasts, a bit like asking for opinions on a Ford Transit Vs Ford Fiesta. 
 

RASA can’t be used visually, only photographic. Very fast though at F/2 and sucks up photons like nothing else.  Will produce nice images in minutes rather than hours. It is a wide field scope though and suitable for larger DSO. Not the best for galaxy or small planetary Neb imaging. Not for planetary or lunar imaging due to short focal length and optics are not diffraction limited.  
 

Edge is more versatile, can be used visually or photographically at F/10 native, F/6.3 with reducer or even faster (but not visual) with a hyperstar accessory so can do wide field images. Good on galaxies and smaller DSO if mount up to it.  Great for planetary and lunar imaging.
