Can someone suggest best dividend ETFs and is it better than investing in growth etfs like S&P500?

Can someone suggest best dividend ETFs?
Also how much one should invest in dividend vs growth?
I am planning to buy dividend ETF in Roth IRA so I don't get taxed on the dividends.
I am only aware of SCHD as one of the good ETFs for dividends.
I have most of my investments in stocks and FXIAX currrently. Also, is it a good idea to buy SCHD in 401k?
