I have a TC Flashback X4 because it’s basically a much better sounding DL4. Since I’m pretty much only gigging as a bass player these days, it lives on my music room floor. Mainly for, err, playing with myself.
The delay I like best, though, is my old (modded) Deluxe Memory Man. Highly impractical (large and very analog), but it has a lush texture I’ve never heard in any other pedal, and it’s just the absolute best in trippy self-oscillating silliness. It’s on indefinite loan to a friend because I’m afraid I might sell it otherwise.
