Probably better to go rabadon for he additional damge AND heal than spirit visage.... Remember the heal on your ult depends on your damage.

I didn't do the maths exactly but very roughly, if you assume for simplicity that rabadon gives roughly 100 AP (it actually gives way more), it's 20 more damage every second on your ult, out of which you heal for 75% of that damage = 15 more hp per second. Spirit visage on the other hand increases your healing rate by 15%, so if your ult does about 100 damage per seconde, you get 15 more hp per second too.

So as it seems, rabadon is way better (because it gives extra damage as well) if you can afford it. In terms of healing power only, it's about the same.
