SCHG we like quite a lot. It is large, liquid and with low fees (0.04%). Its performance has handily beat VOO and VFV. This has been due to its focus on growth, and if the market shifts from growth to value (as it does on occasion) we would not expect such strong outperformance. It has about double the S&P weighting in technology, so investors need to be comfortable with that. But we would consider it very solid overall.
