And i'm trying to discourage him

I know it all comes down to preference at the end of the day but i'm sure there are facts to back it up aswell, which is all i'm interested in.
I believe the K70 uses ABS keycaps which are the less admirable ones?
What other specs could be used to count against it?
aswell as alternatives that would be better to replace it?
I have suggested the quickfire for the customisation and comfortable layout.
He doesn't need macro keys.
He is interested to see what you guys reply, so, fire away

Thanks!
