Just my two cents:
When you design (both visually and technically) your site, put yourself in the place of a viewer, and think how does a viewer wants to visit your site; do not make the mistake of thinking how you want viewers to visit your site, because that will make visitors go away [I'm probably on the radical side, but I tend to immediately close any site that: has music, has a long (skip-able or not) flashy intro, resizes my bowser's window, ...].
So, back to the question at hand: what is the intended audience of your site? do they prefer flash sites?
