Perhaps it's the fact that I grew up with Gmail throughout my education (and now my career), but most local clients lack one key feature - quick move!

My entire workflow around emails is based around opening & reading them, and then using the "Quick Move" button in Gmail to move it into a specific folder by typing the first few letters of the folder and hitting enter.

I know there are extensions for Thunderbird like Quick Folder Move [0], but I find these can be buggy, slow, etc. I presume these are just the realities of dealing with email providers who'd prefer you use their webmail clients rather than Thunderbird et al.
