I've always heard great things about Yahoo Finance and I keep the Android app as of recently. They notify me with videos / articles about what's going on in finance which I find handy, it's not too much of it thankfully.
There are plenty of gaps in what Google do that Yahoo! do or did better (stocks, sports, news, weather, chat, groups etc). It's a shame they focused on competing against exactly where Google were the strongest.
I am not sure which company the they is in your second sentence. I think you mean Yahoo and they do have some good services. I haven just always used google products (remember iGoogle?) I have set up yahoo finance and it is lovely but it is just a (small) pain to jump to another site/app ect.
And what strikes me as a finance professional is that I can get live stock prices from the free yahoo finance website, whereas my expensive bloomberg terminal only has 15min delayed stock prices...
