Vios 1.3 versus 1.5

[dr. d]

i have a question.
somebody asked me, which is the prefered vios, the 1.3 or the 1.5? MT or AT? preferably 2015.
the person says it is for two people inside, city driving, mostly. the impression i get is that he wants ease of use/driving, and cost efficiency.
i'm an innova person, so i don't know what to say.
a little help, please.
thanks.
