The main benefit of a Nitty Gritty, VPI, SOTA or similar device is speed: I can clean an LP on my Nitty Gritty 2.5 in about 40 seconds. I do use Disc Doctor in really stubborn cases, and it works quite well - (although I still use the NG to vac-off the rinse water). The Disc Doctor method is, however, quite a bit more time-consuming - takes me at least 5-6 minutes per LP - - once I get into it.
If you have a lot of LPs - or are planning to purchase a lot - A Nitty Gritty or VPI machine is a very worthwhile investment.
