If you like the more sporty look, then I'd choose the Endurer Chronosprint.
If you like dressy, then the Octo Bi-Retro.
For me personally, I'd get the Endurer first and then the Octo
When wearing the Endurer, you'll find you'll get a lot of compliments on the watch, especially from non-WIS's.
Cheers,

and had the endurer a while back, i sold both but let me tell you this
the OCTO is a spectacular watch that almost always always got complements more than with the endurer not that it mattered to me but it was someting i noticed
but also keep in mind that mine was the gerald genta version WG with red and blasck dial
i really do like the new BVLGARI GG OCTO and have seen it and tried it a couple of time and do think it is much better and could be sporty and chic at the same time
my vote goes to OCTO
Both are gorgeous, it it was the All Blacks I would go for it! In this case I would go for the Octo, more versatile and refined in the design.
Whichever you choose you will be happy with.
