At a show in the late 80s, I was talking to an artist who was working on a revival of the Archie Heroes for Archie. They were planning to launch the whole slate with, I believe, Len Wein as editor-in-chief. Some, if not all, of the books were completed before Goldwater or whoever was in charge saw the, decided they didn't fir with the brand, and killed the project.

I don't think any of the Impact creators were the same people who worked on that attempt.

I bought a few of these, certainly issues of Black Hood, The Shield and Tbe Web, but the only one I stuck with for any length of time was The Comet. I remember quite liking it, but not enough to have ever reread any of it. I certainly didn't make it to the end of the series.

I bought them all. I thought The Black Hood was the best of the bunch, a lot fresher feeling than the others, with more stylish art, edgier characters, and a cool concept that made the hood itself more than just a costume.
Second runner-up was The Jaguar, especially the first four issues with art by David Antoine Williams, who was a promising talent.
Down a rung from those two were The Comet and The Fly, both fairly conventional super-hero comics. The Fly had the benefit of the very fun Mike Parobeck art. The Comet's artist, Tom Lyle, was competent but nothing special.
At the bottom of the main series from the line were The Legend of the Shield and The Web. I found Shield plotter/penciler Grant Miehm's artwork to be overwrought, and the concept tired. The Web featured art from Tom Artis, whose work was very contemporary but very difficult to follow:

That example suffers from the coloring, but it's an example of what I mean: it was difficult to visually separate the elements on his pages into coherent parts. I've got the same problem with a lot of the overpopulated cartoony manga-influenced art I see. The Web was a team, not a single hero, but I don't remember any of the group standing out as distinct characters.
Of the rest of the line, the team book, The Crusaders, had some good talent, and I enjoyed seeing its take on some of the other dormant Archie Comics properties like Fireball and Captain Commando.
I don't remember much about the Impact Winter Special, which featured some short stories of the characters who already had their own comics.
Who's Who in the Impact Universe was a bit of a disappointment. padded with too many pages devoted to supporting characters, including one, who, as I recall, died after two appearances. Who cares?
Finally came The Crucible, a miniseries that wrapped things up with a darker tone than that which had characterized the line.
Along the way, there were some other superheroes who turned up as guests or backups: Bob Phantom, Blackjack, The Hangman, and The Fox, as I remember them, were all more interesting than some of the ones with their own series in the lines, and I had hoped to see more of them...especially the Hangman.
One other thing: in the early issues of the line, almost every character had to face some kind of a cyborg villain. I wrote in a letter (Jaguar #7) voicing my suspicions that this was a lead-up to a "new, more literally Steel Sterling." It wasn't, but I was at least pleased that the editor replied that he wished they'd thought of that!

In my reviews of Wizard: The Guide to Comics, one of the early indications I found that the market was headed in a bad direction was when DC chose to cancel the Impact imprint. As columnist/editor Patrick Daniel O'Neill lamented in Wizard #11, the line was selling reasonably well and was reasonably popular, but it was a series aimed at kids buying from spinner racks when the market was beginning to direct its energies towards older readers and speculators buying from the direct market. DC felt it needed to concentrate its energies there instead.

I did buy DC's revamp of the Archie heroes in 2010 & really liked them. I enjoy reading the more obscure heroes from the past.

Thanks for the correction, there! I should've noticed it wasn't Artis on that cover, I just trusted the mislabeled site I snagged the image from. I actually appreciated Artis's work in many ways, and I was disappointed to learn that he had died. 
So here's a real Tom Artis cover:

That one also illustrates my point, I think. I can look carefully and figure out what most of the parts here are, but it just doesn't "scan" easily to me. It hurts to look too hard, but after some effort, I was able to distinguish a helicopter, a pilot, a rotor, and some kind of flying device that this Web agent is using. 
I must say I did like the logo for this. Very fresh design.
