What version of G1 DVD to purchace

OK....so here is the "problem"
I know there are multiple versions of the complete transformers G1 seasons 1-4 on dvd(sometimes + the movie) and am curious as to opinions as to which is the overall best version to purchase.
1.rhino release(were uber expensive) had the shiny foldout packaging came with a g1 lithograph
2.chineese version(default chinese language but can change audio track to english) came in metal tin with keychain and dreamwave style postcards
3.till all are one version(giant purple box with matrix on the front) 120$ ish for all 4 seasons
4.shout factory release(approx 20$ per dvd package)latest release.
those who have seen or have info on more than one version would be great. Special features and remaster quality would take top honors in the decision making process.
any help/info would be greatly appreciated. thx again guys.
