Well, you asked for an opinion, so here goes:
Neither will "work well" with the stock torque converter.
That's a lot of money and work to put into the motor for nothing more than a healthy sounding idle and a gain in topend power that you might not get to enjoy very often.
My advice is to shelve thoughts of a cam change until you've done the supporting mods and rebuild the bottom end to make you feel safe above 6k rpm. Do you have headers and exhaust upgrade already? If not, don't expect much power from a cam change. Stock A4 gearing?
What you're contemplating here will result in a weaker performing package than a bone stock LT1 with drivetrain and intake/exhaust upgrades.
But.........if you insist, I'd skip the Hotcam. The CC503's better lobes and extra 2 deg of advance don't compromise low speed torque as its higher .050" duration numbers would suggest.
