I classify feats into four groups, but I don't encourage or discourage any option.
Powerful - these are the ones that most people complain are OP, even though I disagree. Great Weapon Master and Sharpshooter are the most commonly associated with these.
Useful - these are ones that are just generally useful for any character design. Lucky and Resilient are examples of this.
Character Defining - these ones define what your character really is about. Lots fit into this category, but examples would be Crossbow Specialist, Healer, and Inspiring Leader.
Garbage - these ones aren't worth +2 to your primary ability (and many aren't worth +2 to your secondary ability). Many consider them trap options, and they will simply never get selected except under strange circumstances. I've tried making them better, to the point of combing the ability of 2 of these, and they still never get chosen.
