Personally, I prefer hard covers. I started out as a kid with GURPS, and am now afraid to open half my soft covers lest pages fall out. It's been who knows how many years, and my poor beat up hard cover of the GURPS basic set 3e is still holding together, albeit with a little scotch tape I applied.... over a decade ago? I was so happy when they switched to hard cover for 4th edition, but now it looks like they've gone back to soft in recent years. With DnD, I love me some nice hard covers. I have a couple 3.0 soft covers, but not many.
As far as art, I wouldn't waste my time buying old school black and white. I've thumbed through the previous edition artwork and while as a kid it may have been neat, as an adult I want higher production quality for my money. I want stuff I can thumb through with my rugrat on my lap and wow her with the pictures. There is a lot of 3rd and 4th ed art that isn't the best, but I don't care for the older art in previous editions at all. Just not my cup of tea. I want stuff that is going to look attractive for years until i have my holographic pop-up books and my personal jetpack for when the flying car is in the shop.
As an aside, i'm also trying to collect the classic boardgames in "faux book box" form to have to pass on to rugrat when she grows up and has little rat bastard DMs in training of her own.
