Please help me choose black bag for work

i've owned both and i love the look of the gryson, BUT, it is difficult getting in and out of; i think the leather straps are somewhat awkward...the bianca is a wonderful bag, awesome leather and fits everything, although some people think the turnlock with the strap closure is difficult...so, i guess it's what you like in terms of convenience...i don't really think you can go wrong with either one!
 
I have the medium Botkier in Bone and love it, but can't personally recommend using it as an everyday workhorse as the leather is so very soft -- it feels too delicate for me to be slinging around on a daily basis. You can fit a lot in it though and the front pockets are great for storing ID/transit cards and keys.
