Considering rolling over a 457 this yr into a recommended Vanguard IRA. Any disadvantages to that?  I see I don't incur the 10% if I take a distribution but other than that.   I have a fidelity 401k to roll and a TIAA CREF 403b to roll.

I might be in the position to fund a 403b and or a 457 again. Big might as its only 2 local employers for that and I nothing lined up. Just throwing that out.

Thoughts?

It depends...
A 457 has some unique characteristics that have advantages if you are in certain age classes, or desire to access the funds before 59 1/2 years old.
You can take distributions without penalty from a 457 at ANY age after you sever employment with the sponsoring agency, you cannot do that with your traditional IRA.  I am not saying that touching retirement funds early is a good idea.
If you have no plans to access the money until true retirement age then there is no downside, in fact there is probably plenty of upside: most 457 plans have a crappy line of available investments (high ER) and / or other fees associated that you could afford in a self managed IRA.
