There are way too many tools for a novice investors. The one I like the most is the watchlist risk adjusted returns analysis. I'm actually impressed when they ask me to specify a "reasonable number of assets as computing power is limited". That means to me that they are actually crunching the numbers they say they're crunching.
Pros
Free tools actually add value
Cons
Sometimes a bit slow. Would like more help/directions on some exotic pages such as correlation analysis or backtesting

Correlation matrix
Pros
The correlation function. I selected this software because I was having difficulty finding correlation functionality in other software that I use.
Cons
A bit cumbersome to navigate. Navigation is not quite as intuitive as I would like. Fewer steps to load and save portfolios would be nice.

Macroaxis made it possible for me to use the tools the big money managers on Wall Street use. That's what the site promises and with their one-week free trial I've been able to confirm it risk-free.
Pros
Comprehensive analyses I can run at any time, all day long
Cons
No account aggregation.
