Google Finance is a much nicer looking product in terms of design, but the data it has is pretty weak.

Yahoo Finance has much more detailed financials for a whole bunch of asset classes. For ETFs it has detailed performance data. For equities, you can get (and download) data on stuff like dividend history, stock splits.

Just see for yourself. Pick a few assets and compare. It's night and day how much more detailed YF data is. The only real thing that GF has going for it is in Google Sheets you can put =GOOGLEFINANCE("symbol") and get the current price of that asset (you can also give it a second argument for other attributes, but the data on offer is pretty limited compared to YF).

I was unaware this existed but when comparing a ticker on both platforms Yahoo offers a lot more information and metrics, it's nice that there's no click bait news articles being shown for every ticker you look up on Google Finance though.

Google finance used to be great and then it went to crap. Yahoo stayed the same. Also let's you export historical prices.

Google Finance looks nicer on the surface, but doesn't have nearly as much data. It doesn't have options for example. I feel like Google had a great opportunity with finance and let it wither like so many other things.

I honestly thought they had shut down this. Maybe they just closed the Api?
