What is your best performing strawberry for zone 8a and 9a?

I am always looking for new varieties to try, especially for strawberries.  I've found that one of the best for me is plain old Sequoia.  

Where I am, June-bearers do best.

I have tried many others and they all seem to do about the same---Allstar, Chandler, Cardinal, etc.

What variety have you tried that does best where you are? And what about it is outstanding?
