I started with DreamWeaver 2 in 1998, switched to BBEdit within the first 6 months, switched to TextMate in 2006 and (finally) to Vim in 2010 after 10 months spent trying every cross-platform editor available at the time.
Vim is awesome but I'm fairly certain I would have switched to Sublime Text if it had been available for Mac OS X at the time.
I tried DreamWeaver a bit, but mostly stuck to HomeSite back then. BBEdit never managed to lure me in. And yeah, I think Sublime Text wasn't available when I switched to Vim from TextMate as well
