Starfish Vs Dernic

I'm currently level 110 fishing, and trying to figure out what SHOULD be a simple question: which resource is more efficient in regards to making money, starfish, or dernic?

Things I want to take into account are: price per oil, demand for the resource, gathering speed, and refine success rate.

At first I assumed dernic of course because less people can get it, so obviously demand and price will be higher. Then I actually tried fishing dernic for a while and it takes 2x as long to gather, and its much more likely you'll get nothing from a node.

So overall, what do you guys think is better?

 

LVL 110: 30% fail, 62,3% T1, 7% T2, 0,7% T3


LVL 111: 28% fail, 64,08% T1, 7,2% T2, 0,72% T3


LVL 112: 26% fail, 65,86% T1, 7,4% T2, 0,74% T3


LVL 113: 24% fail, 67,64% T1, 7,6% T2, 0,76% T3


LVL 114: 22% fail, 69,42% T1, 7,8% T2, 0,78% T3


LVL 115: 20% fail, 71,2% T1, 8% T2, 0,8% T3


LVL 116: 18% fail, 72,98% T1, 8,2% T2, 0,82% T3


LVL 117: 16% fail, 74,76% T1, 8,4% T2, 0,84% T3


LVL 118: 14% fail, 76,54% T1, 8,6% T2, 0,86% T3


LVL 119: 12% fail, 78,32% T1, 8,8% T2, 0,88% T3


LVL 120+: 10% fail, 80,1% T1, 9% T2, 0,9% T3

And then to answer your questions as a whole; Dernic is better, since it has more demand and is more expensive. And you don’t really have to worry about the time it takes to gather each resource since you can get up to lvl 118 (fastest gathering speed) very quickly with bombs.
