Surely that depends on how you use PS in the first place? I know of a professional photographer who typically uses Lightroom but for the rare occasional when he needs to do pixel editing, he uses Pixelmator over an ancient version of Photoshop. The resultant file is still dropped back into Lightroom so he still has all his usual exporting options for print etc.
Everyone's usage is different of course and I apologise for calling you Surely!
