Unfortunately, the taste is probably very similar.
That being said, it'd likely still be a better option, if only because squigs are considered animals rather than sentient beings...
An interesting thing would also be the player characters' reactions. Depending on the individual Acolyte's home culture, some of them might not mind at all, others might be okay with squigs but not Orks, yet others would regard any Orkoid meat (including squigs) as unclean for spiritual reasons.
Out of curiosity, how did the PCs react - was there an argument within the group?
