According to css has better performance compared to xpath and it is well documented in Selenium community. Here are some reasons,

  • Xpath engines are different in each browser, hence make them inconsistent
  • IE does not have a native xpath engine, therefore selenium injects its own xpath engine for compatibility of its API. Hence we lose the advantage of using native browser features that WebDriver inherently promotes.
  • Xpath tend to become complex and hence make hard to read in my opinion

In case of searching for a parent element or searching element by its text xpath would be preferred.
