What are flexIO pros and cons?

Hi all, I am new to NXP MCUs and I was wondering: are there any disadvantages in using flexio module rather than a real UART for example?

I guess it adds some complexity to the code in the configuration part since it is able to emulate a lot of peripherals. Is there anything I should know in the working principle of this flexIO module that could have an impact (I mean a different one if we compare with a regular UART) on the operation (increased consumption, more clock cycles / time to run, ...)?

Thank you in advance for your help!
