Does it make sense to sell an ETF at a loss and buy back a similar ETF with better expense ratios?

For example, I have both shares of VIG and VOO. VIG has an expense ratio of 0.06 and a tax cost ratio of 0.68. VOO is 0.03 and 0.52 respectively. Obviously, I'm not super experienced or knowledgeable at this, but I don't see a downside, but don't want to make some dumb little error that'll cost me.
