I can't imagine why you would pick the 25A over the 30A.  Maybe it's more about which is in stock at hobby king at the moment people buy them.

I've heard that 30A version is the same under many brands like Hobbywing Pentium 30A etc. 

On the other hand, I've never seen another 25A.

I definitely agree, go with 30 Amp, it is most likely because of availability of parts.
