By contrast, the Crows are deep in crisis after last week's sacking of coach Brenton Sanderson.
Gunston did not dodge the issue when the two clubs' vastly different fortunes were put to him.
"Obviously I looked at it (Sanderson's sacking) - and it's pretty disappointing what happened - but they're a great club and they have a great culture," Gunston said.
"So I'm sure they'll find someone right for the job.
"But on a personal note, it hasn't really affected anything I've thought.
"It was a decision I made three years ago and it doesn't make me any happier or sadder that I left.
"They're good people - I always wish them well. It was a tough decision to leave."
"Over the last few years we've just worked out different avenues to goal," Gunston said.
"You don't want to be too one-dimensional going forward and it's great reward for the amount of effort and time we've put into working out our forward setups.
"But it's also the pressure of Paul Puopolo and Cyril (Rioli), when he's there, and also the midfielders who come down and create the turnovers.
