Think of it this way - LSPosed is a
somewhat new version of Xposed. Both are an unofficial Android framework made for changing codes of system apps. By changing these codes, new customization options and features can be added to the Android device using the LSPosed Framework.
-- Most modules that I have
thrown at LSPosed that were designed for XPosed have stuck thus far.
-- Bear in mind that some
XPosed modules just will not function on LSPosed [hit or miss].
