Hands down, Yahoo Finance is a much better site than Marketwatch. I'm picking on Marketwatch since you say that it can replace Yahoo Finance. Here are a few data points: Interface - YF has all the three indices information (S&P, Dow and Nasdaq) right in front of you. MW has this in a small box on the right. While this may seem trivial, over a period of time - YF sticks but MW doesn't. Content - All the content above the fold on YF is related to the markets. If you look at MW , for instance there is an article filling up which airline features you should pay for - totally unrelated to markets and in the main view of the fold. This is not a one time phenomenon, but happens all the time. One of the reasons I stopped using MW. Quote lookup - The quotes are all on the left and the lookup bar is right below the quotes. Also if you look up a stock and revisit the home page, that information is stored - without requiring you to sign up. SO you can just build a portfolio of stocks without even signing up. (Of course, if you clear your cookies this will be lost). Try doing this on MW - The quote look up bar isn't even obvious ( you have to hit on the search button to make it visible). I can go on and on about feature comparison but what I'm trying to get at is - Yahoo Finance is one of the most usable sites when it comes to market information for a vast majority of users interested in the markets. They have carried over the same interface to other geographies as well. For example yahoo finance India isn't drastically different from Yahoo Finance US. So it wouldn't be really wise for a company to just abandon that user base.
