"...is there any inherent advantage to connecting in triode versus ultralinear for, say, an EL34 or KT88?"Yes.
Have a look at the plate curves, UL vs. triode.
The harmonic distortion produced by the tube is directly related to the whether the grid lines are evenly spaced along the load line.
The more even the spacing, the lower the distortion. (not necessarily the distortion of the amp as a whole but the distortion produced by the output tube)
BTW, CB makes some very good points below.
