hmmmm. hard choice. i cant get tell you what is best for you, but personally i enjoyed my hogue ex-01 tanto more.
heres some things i liked and didn't like

the blade thickness
pocket clip
the smoothness of the engagement/disengagement of the lock. it didnt hurt your finger after you unlocked the knife 5 times in a few minutes lol
s35vn was a nice steel, honestly as long as it doesnt rust if i put it in my pocket wet (my hands are usually wet from my job) and stays sharp steel isn't something i t doesnt matter to me much as long as its not pot metal
the blade sharp and verall design was great
dislikes
the blockness of the knife wasnt totally for me
it filled my hand out but not perfectly for my thinner large sized hands
i wasnt a fan of the factory g10 scale at all
*the knife was smooth, certainly, but it wasnt SMOOOOOOOOTH if that makes sense. it has low friction in the pivot but it wasn't what i expected

aluninum handle shape fit my hand perfect
tanto blade i really liked, the spine has some really cool grinds on it
the pocket clip was perfect, and the knife entered and exit'ed so quick
*in my line of work time = money, when i need my knife i need it quick, i need to make a quick cut, and i need to get it away safely quick. this knife did all of that
i love 154cm steel
the stonewash was fantastic
the locking mechinism was wonderful too. not lefty friendly but I'm a righty
the knife packed a huge blade into a little handle, and you got alot of blade for the weight
the blade was so smooth when opening and closing
dislikes
the lock up was tight, precise and consistent yet it still felt somewhat like a toy button to me
the aluminum was prone to small scratches from metal.
last dislike is that i sold mine lol :/
overall i enjoyed my ex-01 more, but try to get to a shop and get a hands on with both before deciding
