As per being the best or being the last table, that is an entirely different question.
If you are asking in the $4k price range is that the best table I can get now that is a different question.
Personally you have to look at the competition and then weigh the pros and cons.
For example Rega RP 8 offers a killer package with the outstanding Alphetta 2 for $4k the Alphetta is a $1,800 cartidge that sounds like a way more expensive one, so you are getting a killer cartridge for $1,000.00
The Technics has a very clean fast detailed sound that many people like.
As per mats and clamps that is something you will have to try for yourself if you like the changes that thoese things do.
I would try to audition the Technics vs a great table like the Rega and I would also look at the new EAT tables as well.
