I don't think the top ten would've changed since then. Apart from The Office there have been no major all time great sitcoms. Shows how poor sitcom was if My Hero was the best of that year!
The Office and/or G&M heralded a new style in sitcom and gave sitcom a new lease of life but also took us away from what the sitcom was. By the end of the decade the vogue for new styles was bringing in some of the worst sitcoms ever made.
The real trouble is as I see it, the clueless TV commissioners think differently now, they are post G&M execs, and want trendy, clever, edgy sitcoms, or just sitcoms made exclusively by the new wave of comedians and do not trust any writer new or known who wants to go back to the old pre watershed classic style sitcom.
OFAH was and still is hilarious, it wasn't edgy, it wasn't crude, it wasn't risky, just funny. TV has simply lost the plot! (And it's the clueless new execs' fault.)
