Well, Vald's damage doesn't scale so well with ap, but rabadon gives around 220 ap with your build, which trnlates to ~300 hp. Sunfire gives you more hap and some armor, but only a negligible 11 AP. With rabadon you gain around 360-400 damage on a full rotation and heals you for around 100 damage. With Sunfire you gain around 80 damage on pool and 40 damage per second to the enemy team with the aura. So, in 10 seconds you deal a rotation with ulti and two without it, dealing ~800 extra damage with cap and healing for ~200 damage. In the same time you deal 400 damage with sunfire and 160 for 2 pools, healing for an extra ~40. And you stay alive a little longer.

I would say: if you have a particularly tenacious opponent with high burst (but not enough to kill you), go for the first burst and buy rabadon. If you face several average opponents with a lot of ad, Sunfire might be your answer.
