A transformer, bridge and smoothing caps is much easier to fix if it goes wrong.
An SMPS has a lot to go wrong.

That's a good point.

I don't so much mind the weight of linear as inefficiency, but I'm not clear on just what that is.

Any idea what idle and full power losses are with +/-60 V rails?

Average power is low, so I don't much care about the latter.
