Sumana’s claim copies Khema’s in the translation but the Pāli is different. Khema’s should probably read:
‘There is nobody better than me, nor equal to me, nor worse than me.’
‘natthi me seyyoti vā natthi me sadisoti vā natthi me hīnoti vā’
As I read it, Khema’s and Sumana’s claims essentially amount to the same but they are expressed differently.
