Hi all, newbie here. I want to invest in a small-cap growth ETF through Vanguard. I was planning on investing in the VIOG, but it came up with a note to "consider" the VBK as it is a lower cost. VIOG has an expense ratio of .16% and VBK is .07%. VBK also seems to perform a little better than the VIOG, but I can buy VIOG right now at 17.5% off ATH whereas VBK is only 4.1% off ATH. Any thoughts on which to go with for a long term buy-and-hold strategy? Thanks!
