First +1 on it depends on the singer and there is no best choice 4 all.

Secondly, if you like to go for the LA2A I don't recommend the UA reissue.
I meantioned this b4: comparing my well maintained original Teletronix to
the reissue was like night and day.
It sounded as different as comparing an 1176 to an LA2A.
Maybe I was just lucky and got an excellent old one (even they do sound very different from unit to unit).

Thirdly, +1 on the mic choice which to me also is more important.

as usual just my 0.02

same goes for the mic ...
