I agree with you on this, in fact, its not just fair to compare Corolla Altis with Yaris as both are different segment sedans. Yaris can be compared with City and yes, it's far better car than City, but the only drawback in Altis is obsolete 4-Speed auto transmission instead of modern CVT transmission which will give a big difference in fuel average if your daily commute will be everyday school run and groceries etc. But still, if fuel average is not your biggest concern, then get an Altis 1.6 which is better than Yaris in almost every aspect, Hope it helps.
