I haven't played either but going by the demo of the fuzz pedal and the fact I don't really care about echo, I'd say the Death by Audio Supersonic Fuzzgun kicks both their butts.
Oh yeah some guy on youtube had a cool idea for modding one. His idea was to put a second footswitch on there to switch between gate and oscillation mode instead of using that little toggle switch up top. This would allow you to use oscillations for only part of a song (yay oscillation solo 😁 ).
