It all depends upon the priorities If you wish to gain traffic from search engine use the flash very carefully, prefer a hybrid website... main contents in HTML and some presentational elements in flash.. but if you dont bother the search engines, you should go for a flash site, its a great way to add interactivity. Although you may also achive some animation through JS but with alot more difficulty then flash.
That is long in the past; i.e. no longer true.

None of which is inherent to Flash.
No matter how the content is presented, good is good and crappy is crappy.
And, "crawlability" has no effect on visitor behavior.
