XPATH and CSS, which one is suitable to use...

Lot of discussions happen over the topic. But this what I think.. Correct me if something is missed here :)

CSS	XPATH
CSS is more readable. and faster	Xpath is complex to read.
Css is more faster	Xpath is less faster than css
Generally good against Internet Explorer browser for finding the elements	Xpath bevomes slow and sometimes unresponsive with IE.
Getting dynamic loading of elements becomes complex.	Since Xpath has contains, start-with and ends-with functions, xpath works best for dynamically loading of elements.
Maintainace is easy for css	Maintainace becomes difficult with xpath being the complex structure.
Id is defined using "#"	Id is defined using "[@id='xx']"
