Any 'small' phones as good as Xperias?

Looking for some input about this. I hate big phones. My Xperia Z1c is as big as I'll ever use (4.3" display). I have seen other phones this small that seem good, but the specs usually pale in comparison to Xperia compact phones. I know sometimes specs don't tell the whole story, (a 1.2 GHz CPU might work as good or better than a 2.1 GHz CPU depending on how the software handles it), so what have you all found. Do any other small phones stand up?
