Re5 was an incredible game (I'd give it a 9.5) so I was a little disappointed in most of the content in the Gold Edition. 

First of all, I was really, really impressed by "Lost in Nightmares," which put more emphasis on the "horror" in "survival-horror." In my experience, Re5 was more action than horror, so I found the change of pace a lot of fun.  The puzzle-esque boss battles near the end of the episode were truly clever and intense. I can honestly say I've never been more terrified in front of a television set than i was playing "Lost in Nightmares," even after playing the excellent Bioshock 1. That first time exploring the Wesker Mansion is one of my most memorable video game experiences.  

"Desperate Escape" offered much less in the way of new game-play. Much more action-based in nature, this episode felt a little like a rehash of previous levels (particularly near the end of the campaign.) That final minute or two was truly intense and fun, but also got incredibly frustrating on higher difficulty settings. 

I'm not a big fan of "Versus." If online competitive  gaming is your thing, there's a lot of games I'd recommend before Re5's versus. The "mercenaries Reunion" is amusing for longtime re fans, but thats about it.

If you own and enjoyed the original (which i really did!) I'd highly recommend at least buying the "Lost in Nightmares" DLC. If you don't own it, buying the original+"Lost in Nightmares" might be your best bet, unless you're a long-time fan of the series. Sorry Capcom, "Desperate Escape," a few new costumes and character;s just don't warrant a full retail purchase for me.
