LME49860 versus LM4562

[mchambin]

That is for a microphone preamp.
I am mostly concerned about ultra low noise and low thd.
They look the same: 2.7nV/√Hz, 0.00003% thd.
One is +/-17v the other +/-22 v
What' s different, audio quality price popularity availability ?
Do they obsolete OPA627 which is 4.5nV/√Hz ?

I thought LM4562 and LME49860 are the same part.
OPA627 is a dielectric isolate jfet input, different animal.

The LME49860 is an LM4562 screened for higher supply voltage.
