MapleStory Chaos: Profession Recipe Guide

Would using a combination of Gold plates and Topaz jewels yield the same exp rate; and that you'd finish within the same amount of time if you were to use 388 gold plates?
Ex. 200 gold plates and 188 topaz jewels?
Thanks in advance!

200 gold plates and 188 topaz jewels are also OK. But isn't the fact that gold ores are at higher drop rate from monster than topaz ones?
However the prerequisite of the discussion on these is that GMS will hold the event.

Edit: I finished the event and gained the reward in KMS during that event with tons of amethyst plates one day before deadline due to poor preparation and economic condition.
The price of plates raised 1000% at that time. It cost me 80 million meso and only one of my three charaters got the reward...
And found that the dark angelic was sold at 240 million on FM...
Now it is 600 million.
