Not being of the ripe old age of Darren, I have never played the pre-Steel Eden course. That being said, I tend to agree with him, and Brian and Tommy, with the following comments/exceptions.
The Steel holes are 12-17. 1-11 and 18 are fine links golf holes, not great (in toto) but fine and with lots of what Cirba and Naccarato would call "soul." 11 is particularly good. After that, however, things go downhill pretty rapidly from 12 (an OK driving hole and a moderately interesting green); to 13, one of the most ridiculously bland greens I have even seen; to 14, which has absolutely no redeeming qualities. Afte that, however, things to get a bit better (they can't get worse!). 15 is an OK over the water, into the wind to a somwhat subtle green par 3. Not links, but not bad. Quite a bit better, for example than 17 at Pacific Grove. 16, despite the right hand mounding that Brian had showed us looks so funny from an aerial view is a good 4.5 par hole with an interesting two tiered green. 17 is a tough long 4 with a good left to right sloping green with grunge/OB on the right that makes a GIR a real achievement.
As mentioned before, I've played the Eden 4 times in the past 5 year, 2 in tournaments, and latterly one month ago. I doubt if Steel will highlight it on his resume, but as the land he was working with was pretty marginal (more meadowland than links) and the budgets when he was working on it were substantially smaller than they are today, not a complete bollocks, just a lost opportunity.
PS--Steel (operating under the monniker "Steel, Cotton & Pennink") was the official architect to the R&A in the mid-late 1980's.
