As far as these two rods go, they're not much different during welding. The real difference comes with lots of time given to allow micro cracks and other deformations to really form themselves. 7018 is what's referred to as a low-hy rod, this means that it has less that so much hydrogen percentage that is located in another set of numbers and letters that can be found right after the rod identification (i.e. 7018 H4R). All that this accomplishes is less hydrogen cracking after the welding is completed and some temperatures have done their thing. 7014 however is not a low hydrogen rod and so is more susceptible to such cracking.
I hope this helps!

just my opinion BUT it's just a 6013 with more strength. it's got the same drawbacks as 13. give me 7024 any day!
