Atmega32L 8au and Atmega32L 8ai
So, to directly answer the OP's question, These two chips are of the same speed grade, temperature range, and package.  I suppose it's possible there is a difference in...

V-USB and Attiny85
How much bulk capacitance are you allowed to shove into a USB port?  I see two electrolytics on the photo of the breadboard but their values are not visible.

I/O states pre-POR
I've always put a pulldown (or pullup, if pChan) (10k) on the FET's gate when faced with this situation.  I've never seen any unwanted spurious behavior on power up of an AVR...
