The Magic team that lost in the finals was very good. Peak Dwight Howard, JJ Reddick, Rashard Lewis, Hedo Turkoglu and then lots of very competent reserve types like Jameer Nelson, Tyron LUE!, Skip-to-my-Loo (Rafer), Martin Gortat, Michael Pietrus and Courtney Lee. They were in the semis the previous year and inexplicably blew the Eastern finals to Boston the next year (added Matt Barners, Brandon Bass, Vinsanity and Ryan Anderson while only losing Turkoglu, CLee and Tyron Lue).
And I'd augment my earlier point to say the Heat were the best team in the NBA over 4 years so they win 2 titles regardless of which conference they came from. And prior to that the east was a dogfight with all the teams I mentioned taking turns as beast of the east.
Unquestionably though the West has been a gauntlet the last 1-3 years. Even while the Warriors were fortunate with their draw, the Spurs and Clippers succumbed to a tough bracket. But I think last year is the ONLY year that LeBron has made a finals b/c the rest of the eastern conference was relatively weak. Even so, because the Cavs didn't even make the playoffs pre-LeBron and the Heat missed the playoffs post-LeBron (don't give me Bosh injury, they still should have made the playoffs), we have pretty dramatic proof that he is the best. If the conference and LeBron were garbage wouldn't those Cavs or Heat teams at least make the freakin' playoffs?! Heat dropped from 54-28 to 37-45, Cavs surged from 33-49 to 53-29.
