Weird, I was just listening to Forgive Thee about 20 minutes ago, and I almost woke up the wife while digging out some beer from the fridge.
Personally, I think any Cheater Slicks album could be their best at any given time. They're all great, and some fit certain moods more than others (i.e. different kinds of drunkiness or shitty days at work or getting hollered at by the wife for not doing the dishes when you said you would). Been listening to Whiskey and Yer' Last Record the most lately, but that changes from week to week.
