I'll be contrarian. The general wisdom is hold the fund with the lowest fee structure.
However, if the fee structure is 0.07%, that's $70/year / 100k invested. Even if it's 0.44%, you're talking about $440.
The fees on most funds are small enough now to not matter much. It's worth shopping for lower-fee funds, but the more you go below 0.5%, the less it matters. If I save $500 per year for 50 years, that's $25k+interest, which is kind of the breakpoint of where it has practical impact on e.g. when I can retire.
For index funds, the important measure is the tracking difference [0] anyway. While the costs contribute to it, different ETFs on the same index differ in their typical/historic tracking differences beyond their differences in nominal cost.
guntars did the amortization on $25k growing with interest (not fees). In other words, the claim is that 0.5% can be significant. Which is true.
When I did the math with my life savings, 0.5% was about the breakpoint where things become significant. $200k would be more significant, so I suspect when I did the math properly, I was expecting to retire in less than 50 years. In 50 years, I'll likely be dead.
I agree that minute differences don't really matter. E.g., 0.09% vs 0.07%; who cares. Differences as large as 0.5% are much more material in the long term, though.
