If you plan to pursue local diving and have the funds then go for the drysuit. I don't have much drysuit experience but the little I have made me want a tropical drysuit even for my warm water dives. Staying dry while diving is wonderful, especial for that SI. And I personally hate thick wersuits. I will dive a little cool just to stay out of a 5 ml never mind 7. But that's just me.
