No, Its not bad at-all, but rear vents and better throw makes city aspire a better choice. 1.2 city has nothing to boast as such.
As for Yaris, nothing is wrong with it's AC, its more than good... specially ATIV X has climate control and is one of the best options in its league, best of luck with your purchase.

With Yaris you get a feeling of congestion, although its reasonably wide, perhaps its shorter wheelbase shortens the dashboard that makes you feel a little congested. thenagain, if you move down to alsvin, you feel you are sitting in a hatch back...
