LXLE is more than a slightly altered Lubuntu or LXDE system based on Ubuntu. Each program if need be is customized for style, features and efficiency. SeaMonkey and it's components are a good example of this. Not every program is altered but all programs are inspected, if their default states fit the bill it's left alone. If not it's adjusted accordingly.

There is a difference in file size between the 32bit and the 64bit, this is due to some packages naturally being larger for the 32bit version. The 32bit was built twice from scratch resulting in the same exact size. The iso's are the same.
