I'm starting a new design with the ATMega32A.  The chip supports both debugWire and JTAG, and I'm wondering what the benefits and disadvantages of each are.  I'll be using Atmel ICE.  I realize debugWire doesn't strictly support programming, but the interface can also be used for that, so I can program and debug with either approach.  Thanks for any thoughts.

No it doesnt. DebugWire is for AVR with 28 pins or less. On 40 pins or more its JTAG. So you dont get a choice here. Mega32 is JTAG if you want OCD.

Huh. I’m not at my PC at the moment, but I thought the data sheet showed a debugWire block on it. Guess I was looking at another one. Well, that simplifies things. Thanks.
