I've had a Line 6 DL4, Deluxe Memory Man, and a Sunny Day Delay. Each with their pros & cons but I'm fond of each pedal for different reasons.
Now I own a Deja Vu', mainly for the tap tempo + analog warmth all in one unit. I give it an 8 out of 10. One of the small drawbacks for me is getting "musical" oscillation sounds from it.
My Sunny Day Delay was KILLER for this application of delay, if it had a tone control, tap tempo, and stereo outs it would be my favorite.
The Deja Vu' has all of these (except the "tone" is actually a balance between digital & analog, but close) and is absolutely fabulous. Not to mention the recording options it opens up with the wet/dry out and stereo outs.
Great delay pedal.
