I don't think you're wrong, I too use Apple's Mail. It works pretty well. It's got a good filtering system that can sort incoming mail properly. It doesn't try to make e-mail into anything but e-mail. It also integrates into Spotlight/QuickLook so searching for mail messages can happen outside of Mail and has all the expressiveness of Spotlight. From memories long ago of using Outlook and Thunderbird I think I can see where people get a hate for e-mail clients. I don't remember either of those being particularly good clients. They've likely changed over the years and could be better but I have no desire to drop Apple Mail.
