It's a while since your query but... I had an original 201 (grey box) when they first came out, hence my interest in the recently reissued 201. It's been many years since I had the original but it sticks in my memory as it was the first (and only) pedal I had around 79/80. The original was quite noisy but the phase was a bit more defined than the reissue. To my thinking the reissue is a much better pedal, both in sound quality and the modern appointments such as 9v 2.1mm and LED. I've sought out a few of the originals (or older reissues) of the recent DOD reissues and have found some to be just different sounding (the Envelope Filter and Comp) and others not as good (the original Phaser and 80's reissue of the 250 OD). If you can pick them up cheaply they are definitely worth a try, they were quite well made in very solid boxes but personally I wouldn't seek them out and pay big bucks - The new reissues are generally a better option.
