One of the reasons is that serious knives used to be made for chefs, and chefs were mostly men. (cough cough) So they're for bigger hands and male strength and I never realized that the fatigue I felt after doing a lot of slicing and dicing didn't have to be there. Or that so much ergomics go into knife design. The first time I held a Global, I went nuts: it was one of those experiences where the proverbial sun comes out and angels sing. WOW did that knife feel good in my hand, like it was made for me. I've kept some of the old hubby knives, in particular a cheesy brand bread knife I inexplicably like a lot, but I've mostly replaced most of my early knives with Globals (who make several different grips). And not only do they feel good in my girly hand and look pretty hot, they hold an edge VERY well.
A friend of mine has Sabatiers, loves them. I haven't worked with them but I love saying 'Sabatier'! Not familiar with the other brand you mention.
What I do recommend is that you go to a good knife store IF there's one where you live and it's safe to do so, and just handle the knives. Look for one that gives you the experience I described above, that feels balanced and let a good knife seller help you evaluate what balance really means. If I (and my husband) had done that to start with, I'd have never had those crappy old Henckels.
