Because it was considered the "peak" of the show by most people.
Although I thought it was still really good for season 8 as well (with a good climactic battle there as well).
After 8, it had some problems:
1. They ran out of bad guys. At the end of season 7, they defeat Anubis who's the "big bad guy" and pretty much end the long running condition of "Earth can be wiped out by any random bad guy who comes along", which was the premise for a lot of the storylines.
2. At the end of season 8, the put the final nail in the coffin of the Gua'uld (however they're spelled). And then defeat the replicators (finally). Bad guys all gone!
3. O'Neill is promoted to general at the end of season 7, making things "akward" for season 8. But season 8 was kind of a "wrap up the loose ends" season, so it worked.
4. Richard Dean Anderson left the series at the end of season 8 as well. So. Um... No more main character.
5. In season 9, they bring in two new characters for the team, with all the attendant problems that character replacements entail.
6. At the same time, they had to figure out what to do with the series now that they'd essentially "won". Their answer was to create a "badder bad guy". While the Ori (Auri?) are kinda cool, it was a pretty obvious "we need something new and nastier then the previous bad guys" approach.
7. While the storylines have been "ok", seasons 9 and 10 are looking to essentially be a couple seasons tacked on to the end of a different storyline. You could literally buy the 1-8 boxed set and feel you got a complete story.
8. Did I mention that the Ori are kinda too much with the "we need to make badder bad guys!" approach? The whole show just has a different feel to it. For most of the series, the earth people were technologicall inferior to most everyone else in the galaxy. After season 7, suddenly we've got ships that are better pound for pound then most everyone else, and an ancient defense system for earth. So they had to up the ante with a new bad guy. While their solution wasn't "bad", and at least ties into existing storylines and events, it's just got a very forced feel to it...
I'm actually enjoying Atlantis much more then SG1 right now. Which is a total reversal from when Atlantis first came out. Mainly I think because the McKay character is just fun to watch, and they've finally gelled their characters together in a way that feels right. Wheras SG-1 lost O'Neill, and have never really felt the same since.
