DD3 japan here, tried alot of anolog ones, found them great for those huge sounding 70's delay solos but thats it. Very neutral/silent/no-tonesucking stompbox IMO, short delay times can get you a decent enough reverb kind of sound. Offcourse youll get a bit more out of several different pedal, but this is a nice allrounder IMO.
The japan versions are said to sound a bit warmer and have a bit less pronounced effect. I myself found the recent ones to sound a bit crispier, so i do agree with the general opinion i guess. So basically a very nice and afordable allrounder, if you need those 'huge' sounding delay effects(i could do that with dd3 and rev on the amp btw), better look on.
If your trying them out by the way be exeptionally carefull, alot have some weird oot sideeffect of shift the pitch all over the place when changing the settings or even suck alot of tone for that matter.
EDIT: just a sidetrack, if you can do with only reverb and chorus, try out the AD-3, its an acoustic guitar processor, but i also use it for solid and it is an absolute tonewizzard if you ask me.
