In the end, do what you want. Its your costume, your effort, money, time, etc... You should look the way you're happy looking.
For me, I went with the RoTJ Special Edition version simply because I loved the look of it. It was the look in the museum exhibit, it was the look used in all the promotional materials that were around when I started the suit and it combined the best helmet with the best suit. A win, win.
