Most "best reading pen" lists rank on spec sheets. That is the wrong axis for a dyslexic reader, where the question is almost never raw OCR accuracy — it is whether the pen reads aloud without a phone in the loop, and whether a child will actually pick it up a second time.
The short version: standalone pens (Max, PAL) win for independent homework because nothing has to be paired, unlocked, or charged alongside them. Connected pens win on price and on classrooms that already run one device per student.
