It's not the pedal I use the most but my Echo Park is the where it's at (with 2 tables an a microphone).
It's got great "classic" tape, analogue & digital delays
+slap back that sounds almost as good as the the "Double Track" setting on my EH Poly
+swell setting which does Boss Slow Gear sound
+reverse delay that you can take the dry signal all of the way out
+sweep mode; which I don't think anyone else does
and it's got a trails on/off switch (which I always leave on) so yr echos don't cut off
