What I like best about Chrome is its speed. The word Niue exists in many languages and this expression is one of the worst performers on OmegaWiki. With Chrome it is significantly faster. With processing done locally, Chrome makes a big difference.
The other thing that I like about Chrome is the fact that it is Open Source. Google explicitly invited the "other" browsers to borrow and steal from what Chrome has to offer. In the same way, Google happily indicates that Webkit and Firefox are part of Chrome's pedigree.
I love Firefox, it has features and extensions that are must have for me; spell checking is one such. With Chrome being the first iteration of a beta product, I think I can look forward to extensions with confidence. It is great that the browsers world is becoming even more an eco system where new developments are shared and where the scene can evolve and mature with multiple players having temporary advantages. It is the user that will benefits most.
