Yes, I went from the Xperia Z1 Compact to the XZ Compact...and not only is it larger, but worse is every way except raw speed. It is more buggy, difficult to find a screen protector that stays on, screen often freezes, the large size makes it far less comfortable to use. I am seriously considering buying another Z1 compact even though it's years old and slower with an out-of-date Android...but the form factor and reliability was unbeatable.
