I'll put my plug in for the doppler. I like the fact that it gets me in the right plane without having to look at a screen. I just have to find the depth on my own. With doppler and a through and through technique my success rate is pretty high.
One of the peds anesthesia attendings I worked with in residency that did lots of peds cardiac loved the doppler for peds a-lines. Especially on the <10kg kiddos. He rarely used U/S for his a-lines but usually doppler. He always used U/S for the neck line though.
