I will give this a whirl in a few ways.

In order of Xs and Os:
1. Bowden
2. Dye
3. Tubs
4. Malzahn
5. Chizik

In order of overall coaching (recruiting, Xs and Os, gamely prep):

1. Dye
2. Tubs
3. Malzahn
4. Bowden
5. Chizik

Dye is the best of the last 5 and arguably one of the best ever at Auburn.

Bowden was a great field coach but miserable little frick and the players hated him. Facts are facts though, the dude won a lot of games and did a lot of really good things.

Tubs, in my opinion, was more a recipient of a down period of the SEC. Alabama was pretty irrelevant, recruiting wasn't held with such regard, Spurrier left UF pretty early in Tubs' tenure, Tennessee was still good and the rest of the SEC really wasn't amazing. 2004 was a great team and possibly one of the best, not only, in Auburn history but SEC and NCAA history but the let down of 2003 cost them a chance at the championship. For every great game he won, he lost an inexplicable game that was far more heartbreaking.

Malzahn is a young coach that hasn't been around a long time and I think he can get the job done given time, but will the fans give him time? He was been a part of two national championship games in 6 years at Auburn and I don't think that is a coincidence.

Chizik deserves credit for assembling a really good coaching staff and winning a championship but he also shoulders the blame for falling so far so fast. he lost the team completely two years removed from a championship and that loses a lot of respect from me too.
