Customized Android ROM is necessary when we focus on android device for a specific market. A custom ROM can give you a faster and slimmer version of the operating system, besides that, custom ROMs can offer much more than that. With commercial friendly open source license, Android is very open to all kind of customization, we can tweak it anyway we want that is why comparing an HTC device to a Sony to a Samsung is like looking at totally different species. Although, all of them run on the same Android, they are quite different from each other as manufacturers have customized the OS to differentiate the devices.
A stock ROM is the version of the device operating system that comes with your device when you buy it; it is what the OEM releases with a phone or tablet.
A custom ROM is a customized version of the OS, including the kernel (which makes everything run), apps, services, etc.everything you need to operate the device, it is customized by someone in some way.
Why would you want a Custom ROM on your Android device?
When you focus on manufacturing/customizing android device for a specific market, then we may not need android tailored with special requirements. We might need to remove some of the features that the stock android provides and we need to add some of the features in the android ROM. The custom ROMs allow us to uninstall any unwanted apps or they do not include all OEM apps by default, resulting in better performance. Also, one can restrict background processes and does not allow any app on auto-start mode in a custom firmware.
