(Just looked it up...the above image is from Uncanny X-Men #246....ironically Jim Lee's first ever credited X-Men gig...one can tell from the way the feet are skillfully hidden from view. I might be from the ADHD generation, but at least I can spot a Lee from a mile away. ;p )
Here's the thing about the era of the "Superstar Marvel Artists" it was dead by 1993, when both Lee and Leifeld left for "greener pastures". Oddly enough, if Claremont had just stayed where he was and not ticked off Bob Harris, he might have had the X-Men back by 1995. The truth is a lot of Claremont's work getting pretty stale by the 90's - at one point he'd written three mind control archs after the other. I think he needed a change and even he knew it. Excalibur would've been a great place for him if he'd decided to stay.
Also, Lee was pinch hitting for Marc Silvestri on certain X-Men issues by 1989 - so some of the Aussie period, could've been Lee, just not being credited (he is actual credited on some). Marc Silvestri, weirdly enough was one of the "super seven", but X-men fans seems to give him a free pass they don't give Lee. (This also casts new light on Claremont's claims that he couldn't work with the new young artists, because they were too slow and wanted too much control - he seemed to have worked happily with both Silvestri and Lee in the late 80's and it was never a problem.)
As for Scott Lobdell, I urge you to read his earlier X-men stuff. Uncanny #303, as I mentioned, most people confuse with Claremont. At the start of his X-run, Lobdell pretty much tried to sound like Claremont, because he knew that was what fans wanted. His GenX run has some of the most original stuff ever done in Marvel comics - it's a teen comic, but his not talking down to the audience (like Hama), his expertly moves the audience through the complex story and the characters, sprinkling little hints about their past through the years, much like Claremont did. In all fairness, it seems he and Bachalo had full creative reign on GenX, so they could go as dark and indie as they wanted.
I find people who hate the 90's either do so because their favourite character got moved out of the main X books (Kitty, Nightcrawler, Dazzler, etc), their favs got altered (Psylocke), or that they never could get over Claremont leaving. And I get it, all these things are totally valid reasons for not getting into the 90's. I have a similar problem with the middle '00.
The bigger problem the 90's X-Men had was some terrible calls made by Bob Harris later on. For example, moving Scott Lobdell permanently off GenX to mainly focus on the X-Men again. He'd done a fine job standing in for Claremont years before, but when he came back things just weren't the same and you got the feeling he longed for the freedom he had on GenX. Other bad Bob calls: placing Larry Hama on GenX, leaving Hama on Gen X when it all went south, letting X-Force just slowly die off, not fixing whatever was going on in X-Factor, not placing more focus on Excalibur which it deserved, starting the trend of writer shuffling, willingly letting writers do shocking reveals of characters back stories with no actual planning, (Gambit, Joseph, the twins) just to get the sales figures up.
In all fairness to Bob Harris, he wasn't solely to blame, the other X-editors are as responsible as he was. Marvel was starting the new "universe crossover" era and that's where the wheels really fell off the X-cart. The late 90's wasn't a good time to wear the X. Plots got terrible convoluted to tie into the next "BIG" universe altering event, page counts starting going down because of the rise in printing costs and the move to glossy paper stock, the comic collector bubble burst, the audience was shifting to other things and Marvel didn't know how to compete.
I often see people placing all the blame on either Lee or Lobdell - they've kinda become fan shorthand for reasons not to like the 90's, but Lee started in the much lauded
80's and was gone by the early 90's (some of Joe Madureira and Andy Smith's 90s stuff is much worse), and Lobdell gets blamed for the whole era,
when fellow writers like Fabian Nicieza, Mark Waid, Larry Hama, Leifeld (lets not forget this "renaissance man" wrote as well) and even Claremont (the mastermind behind The Twelve) got away with murder...
But it just comics at the end of the day and I just want a quality product - we had some awesome years in
both the 80's and the 90's, lets just enjoy those and ignore things like Schism, BotA and dorky, over-powered, plot device kid of the week.
