My quick take is, on the downside, you have to pick the particular MINT ISO that you want at download, there are different ISOs for different desktops and for 32 bit and 64 bit versions. As a result the ISOs are smaller, and they also contain fewer of those applications that you never use. Of course, you can still install any application that you want. On the upside, browsing with Flash still works, and you don't have to try to install extra packages that don't install properly.
If one wants an installed system I still recommend Debian over any "Live CD" or DVD. But if what you want is a Live DVD that you can boot and use right from the disc, I'm very happy with Mint.

Verifying of md5 checksum and burning a CD at slow speed are important.
