With TD Ameritrade giving $0 commissions on stocks and ETF's. Would it be the best brokerage around as of yet?

The best is subjective based on your needs.

To me, as someone who at most make about 0-4 investing decisions on an average a month, any safe platform is alright.

For somene who does heavy trading, I would assume the best would depend on the lowest commision.

So it is subjective.

Focus less on those and focus more on making the right decision in the market.

It is hard to define any broker as the "best brokerage around". Each person has their own set of needs and different brokers have their pros and cons.

For example, TDA only has US market access, so those wanting to trade in other markets will have to consider other brokers like IBKR, Tiger and SCB. The exchange rate that TDA uses is also unknown (need to request), which could add up as a hidden fee as compared to IBKR's spot rate.
