Personally I would be careful with such " test / reviews " and I havent read that report but I heard from my friends, that the Teres is a nice table, but far from being outstanding.
I never owned a Triplanar but I own a Graham.
And I checked a Schroeder Arm. Both on same electronics, same cartridge and same turntable ( Basis Debut ).
Both arms were fitted with a Miyabi.
And the Schroeder is not bass shy, that is nonsense. It creates a bigger soundstage than the Graham and sounds in a way natural, but I thought at that time, the Graham has a better high frequency area and a better image.
Personally I think, all these arms above are super, the Schroeder makes sense, when you have a cartridge you really like, because the arm tube can be matched to that cartridge.
