What does the phrase "说不好比起~" mean? I saw this on a reviewer's video, but I'm not sure if I understand the meaning or how you would parse it in English?

I didn't catch everything the speaker said but I remember;


  说不好比起[name of character C]也


From context it seems like the speaker was comparing someone he's recently met (A) to two others (B and C), he said A was not like B, and then he says A is "说不好比起[name of character C]也".
'说不好' is a variant of '说不定' (can't state with certainty= may be)

'比起' means 'compare to'

'也' in this context means 'even'


&quot;说不好比起 C 也&quot; = &quot;May be even(?) compare to C&quot;
It is an incomplete sentence, we don't know what quality is being compared between B and C
The following would be a complete sentence:

&quot;[说不好]比起 C 也好不了多少&quot; - &quot;[May] not even [be] any better  compare to C&quot;
好不了多少= not even any better
