It's just a personal preference. I can't tell you why, but I just don't like how all of the programs start with K. I think it looks weird.

It also annoys me every time I try to search for the calculator by typing in "Calc", but nothing is found because I forgot I need to look for "KCalc"

I think at the very least, commonly used applications like "Calculator", "Console", "Mail" should just be called "Calculator", "Console", and "Mail". Not everything has to be branded. The mail application on Windows is called "Mail", the terminal is called "Terminal", etc. They don't call them "WinMail" or "WinTerminal" for a reason. They know most users would find that off putting
