Depending on your brokerage you should have a lot more investment options available to you rather than just leaving it in the 401(k).
I do agree in most cases if one can only invest a limited amount, the strategy you've suggested is superior. My income bracket doesn't allow for a direct contribution into a Roth. I have a way around it, and it's maxed every year, in addition to the $18k 401(k) limit.
I'm also taxed at 39.6% for every dollar I earn at PSA that isn't tax deferred, so the smaller my W-2 income is, the better.
