If you're familiar with OSs, think of IOS as MS-DOS, IOS-XE as DESQview or VM/386, and IOS-XR as Linux or NT.

Hello 

IOS-XE is basically a combination of a monolithic application and a linux kernel. IOS-XE is an advanced version of IOS and pls note that both IOS and IOS-XE share a lot of codes, meaning that both have similar codes unlike IOS-XR which is based on entirely different codings.

IOS-XR is based on QNX(QNX is a Unix type OS). The applications of IOS-XR has been seperated into different processes and if any one process stops or malfunctions ,the other processes are not effected.

From practical experience, they are just 2 different IOS.
Depends on your luck whether you will have better or worse quality of life between the 2 OSes.

That's a compromized way to say about them.  My actual experience is worse with IOS-XR.
