Sarasota is full of 'indian chiefs' where Venice and Bradenton is more for 'indians'.
I am comfortable in Sarasota; been here 23 years ... but truth is ... I am an indian at heart.
I settled in Sarasota for business and business connections and it has served me well.
If I could do it all over again, I would settle in Venice, on the island.
It has a quant downtown area and is more down to earth. It also attracts a lot of Italian Americans (it is Venice, after all); they have a terrific and very popular Italian Heritage Fair every year. Yum. (Manga)
If you like fine restaurants ... and the performing arts: theater, orchestra, art fairs, etc .... you will prefer Sarasota.
If you spend some time with a good realtor ... chatting on the phone if not in person ... you will find what fits you in either Sarasota, or Venice.
Bradenton has crime issues and bad traffic. Did I mention the crime?
Good luck to us all.

Note: We are due in this area for a storm with flood damage. It has been about 90 years. Check a flood map before you buy. (That could be an issue in Venice)
