Odex vs Deodex
Theres plenty of debate over what is faster/better to use, im not going to take sides in this one. This is just information about what the differences in the two are, try for yourself.

Deodex basically takes the odex file and stuffs it into the apk as a classes.dex. First boot it dissembles the file into /dalvik-cache (i believe). Now there is basically 2 copies of the odex, one in the apk one in cache. This makes it "portable". This allows modders to work on the apks & easily change stuff. If you want themes or stuff like lockscreen fixes you MUST use Deodex.

Odex is how things come stock. It takes up less room but making modifications or taking apks from other roms is hard. You cannot use themes with this version!! To see odex in dcupdater you must go to menu -> configuration -> rom update settings -> display all roms & display experimental roms. Its marked experimental to avoid confusion because themes in dcupdater will not work with it.

Odex - 374 MB free after fresh wipe without setting sync accts up
Deodex - 329 MB free after fresh wipe without setting sync accts up

I use deodex because I like to theme my Hero and EVO. There are some great themers out and it just adds another benfit of "rooting"."
