Regarding bid/ask spread, as long as you aren't buying at 9:30 am, it will never be more than a penny or 2 per share. I tend to favor the liquidity of an ETF so I strictly trade ETFs for free and get admiral expense ratios thru merrill.
I know the bid/ask spread is small on high trade volume ETFs like VTI. But what I said is still true. It is strictly cheaper to buy admiral shares of the mutual fund at Vanguard than ETFs at ME (or anywhere else for that matter).
This small detail is useful as a tiebreaker, but otherwise pales in comparison to any other reason to use mutual funds over ETFs, or vice versa.

Unless you're day trading, how exactly is an ETF more liquid? (I'm assuming you're not a day trader, because even most of the active traders I've seen on this forum aren't day traders. Also, you only get 30 free trades a month with platinum anyways). Sales of ETFs and stocks are subject to the (T+3) rule, as opposed to the mutual funds' (T+1) rule. It takes two more days to move money from ETFs to your bank account. That makes ETFs
less liquid than mutual funds. Unless you're day trading and you want to say sell VTI in the morning, buy VXUS around noon, and then sell VXUS in the afternoon (since you can't do this type of exchange with mutual funds in a single day).
Most traditional mutual funds will settle on the next business day (known as T+1) after an investor places a transaction (assuming the transaction is placed during normal business hours, and before a fund company’s cut-off time). This means that when you sell a traditional mutual fund, you can generally withdraw or transact your money again on the business day after you place the sale. Stocks and ETFs on the other hand settle on the third business day (T+3) from the date the transaction is placed. Because of this, there is a possible delay in being able to move from one investment vehicle to another.
