Hello, and welcome!
Not only is Linux Lite itself both smaller and faster, but at right around 700MB, the ISO is smaller as well. One 'XP replacement' distro I was considering prior to my discovering LL was not only over 3 GB (it had several desktop environments and window manager options bundled in), but the MD5 checksum was also incorrect - despite my downloading it several times.
The DL was probably OK, but if you can't get a valid checksum to appear out of something, why bother with it in the first place?
