I suppose linear-tracking tonearms (where the back of the tonearm slides leftward as the record plays, keeping the tonearm at an exact 90 degrees and thus the stylus at a perfect tangent, which is how records are cut) are best, since the usual pivoting tonearms are inherently slightly out of alignment at the beginning and end of record playback. But in practice this is generally unnoticeable in either record/needle wear or sound quality.
I don't see how S-shaped vs. straight tonearms have any effect on cartridge placement, much less being "bad for records". The cartridge winds up in exactly the same place and angle with either.
