Best Season(s) of SG1

For those of you who watched SG1, my favourite seasons were seasons 9 and 10. I honestly wish the show had gotten a few more years out of it after that because I loved the direction they took the series with the whole Ori plot and everything. It was pulled off better than the whole Gua'ould thing that pretty much the rest of the series focused on. But yeah, what were you guys' favourite seasons?
