I think after reading many posts about people who have tried many switches I have come to realize physical interfaces are much like graphic interfaces.
I have made quite a few GUIs for various MMORPGs and software I have written, and one important lesson I learned from taking user feedback was this; An interface can be superior in function, layout and feel, but it never feels right straight away. It takes time to adjust and grow into.
My UIs were always very centric, so the most important bits are staged around the main work area. But a typical MMORPG layout has everything spread all over the screen, which is not optimal. You can change it so it is optimal and people will ***** and complain, but once they get used to the new layout, they hate the old one.
So the same holds true I think for keyboards. Its a mix of personal preference and what you are used to. Now, thats not to say that you will like any keyboard given time, or any UI given time. Its just to say that personal preference must come 2nd to interface. Once you get over that hurdle of change, then its fair to judge the end product.
Given also that mechanical keyboards are expensive, they come with a bit of buyers remorse and buyer fanboism. You just paid $100+ for this thing and you expected more, or you just paid $100+ for it, and you're going to like it damn it! If you are lucky you are delighted with your purchase, but you will always wonder if there is better out there. Much like relationships can even be =p The grass is always greener and whatnot.
Anyway, I don't mean to get all philosophical on all of you =p
Soon I will go through this as well in the next week or so once my first mech arrives.
