The distortion which is eliminated or reduced with linear tracking turntables is azimuth error distortion, caused by a conventional tonearm changing its angle as it swings across the record, which means that the headshell and cartridge is not always at a tangent to the record groove. This was especially noticeable at the outer groove (track 1 on an album) and then inner groove (last track on an album's side). Linear tracking also eliminated the need for anti-skating.
There are pros and cons to each format. If you had a very high-end tonearm attached to an equally high-end table (well beyond the price range most of us could afford) then the pivotal format was probably your best choice at that time.
