Smaller bills for me.  

that this has been asked before, but I'll bite! I prefer 100s and 50s, they take up less space in my purse/wallet and are quicker to count.

...... while I prefer bigger the bills the better really my highest preference is the correct amount .

If on tour, it is easier and more discreet to transport a stack of hundreds back home or to the bank than 20s LOL.

Correct amount is most important but..

I definitely prefer hundreds.  Easier to count, and transport.  There are few things in this world I despise more than having to break out a mountain of 20's at the bank to be counted.  

I was always getting crazy looks when I put down the fish bowl filled with coins..  Maybe I should re-examine my cash delivery system... I should have rolled them

For the most part...

It does not matter. Having both large and small bills is helpful; it depends on how the cash will be used. I travel much, so there is a slight preference for smaller bills to take care of tips, cab fares, bell man, etc...

Good question.
