I can speak on this owning a pair of Technics 1200 mk2 I bought new in 1995 and a pair of Reloop RP8000mk2 I bought two years ago. What might be confusing is many DJ turntables are made by the same company now, and are reffered to as "super oem", so the small things are changed, like logos, but they come from the same factory. My Reloops weight close to the same amount as the Technics but the base allows for more rumble through the feet. If you tap the body, you can clearly hear this compared to the Technics.

The tonearm on the Reloop has bearing that have a small amount of play, on my Technics, they are extremely solid after 100's hours of play time. But the biggest issue is the Reloop has the flutter at 0.5%, while the Technics at 0.05%. Doesn't sound like a huge issue, but when playing a song on Reloop, the beats per minute will fluctuate from 100 to 100.5 to 99.5, non-stop. The Technics has the same flutter but at a much lower tolerance, so you don't see this appear. Performance, they both do well on startup and stop, and of course improved RCA jacks.
