Spacebed J in 772ER vs. Ultimo J in 772 (3 class)- which is better seat for HKG-SIN?

I know the IFE will be better on the Spacebed, but want to figure out which is the more comfy seat for a 4-ish hour flight (though both may be adequate, I hear that UA folks think UA p.s. J (recliner) > UA p.s F (Spacebed clone) for sitting). Since both are daytime flights, don't plan to nap.

 

I have experienced the SQ Spacebed and the UA C Recliner many times and can't think of any reason why the UA seat would win.
