It helps if you actually say for which platform
From my experience developers are terrible artists. Hire an icon designer.
In my opinion the best balance of features for money on Mac is Pixelmator.
Windows !
On Windows, AWIcons pro is my favorite. The interface looks old, but it just works very well. Better than the dozen or so others I tried when I was looking. I think they give it way with the icons they sell, although it has been at least 5 years since I purchased, so things may have changed. www.awicons.com/icon-editor/
Pixelmator is awesome image editor (including icons). It also does PSD (Photoshop documents) which makes it great when dealing with digital artists.
I am using icoFX and Axialis IconWorkshop.
icoFX has more features and is easier to use than IconWorkshop. Axialis has the advantage that it has a lot of icon libraries which are very usefull. The amount of icon libraries is expanding every two months with new icon sets. When you are a registered users, you pay only half for the icon sets.
I also think development on IconWorkshop suspended years ago, because for at least 3 years the application was never updated. Still it is a very powerfull and feature rich application. I use both icoFX and IconWorkshop depending on the project.
I use Agama Web buttons for designing my buttons in my applications. I find it easier than creating buttons from scratch, especially when they need a 3D look. I am not sure if this is relevant for you, therefore I mention this excellent application.
