As the title says, i would like to hear some recommendations, cons and pros. I’ve seen both classes videos and i like them alot so if you don’t mind sharing some knowledge with me i’ll be happy 
PD: English its not my main language, so don’t blame me 
Why not just get both of them?)
I heard there isn’t that good a corsair and fencer build, i mean they’re way different, one based on auto attacks and other skillbased
Actually corsair C1 has nothing to do with autoattacks, it’s mostly about hook and utility.
Yet you can always chain skills and autoattacks, so even C2 has decent synergy.
Not considering C3 because it’s only viable for full tank build as a party leader to get maxed JR.
