Is Z3+ worth the MONEY?

Hi guys (especially to z3+ users)! I would like to buy a Z series Xperia phone. So far (aside from the Z5), Z3+ is the only Z series that has a 5MP front camera (front cam is one of my criteria in choosing a phone). My other options are M5 and Z2 (but Z2's front camera is only 2MP..) I am also concerned with its overheating issue..is that really true or just a black propaganda? Is this phone worth the money? Thank you in advance for your opinions! :)
