I have ergo 2's and a pair of Shimano custom mouldable ones which are 3 years old, they are still going strong, really stiff and very comfortable, I actually prefer them to my Sidi's
There is nothing strange about preferring one company of shoes to another regardless of what each company many be. Shoes and saddles are arguably the most personal aspects of cycling *bibs not included* and as a result there really is NO right answer.
For me for example Specialized shoes tend to feel QUITE BAD. The built in wedge causes me pain on my small toes and the outside edge of my feet, basically I feel like I'm squashing up my little toes into the outside edge of the shoe. However, ton's of people love Specialized shoes and they have been just wonderful for them.
I actually liked my old Sidi Genius 5's MUCH better than my current Specialized S Work's because of the lack of the varus wedge. I also prefer the standard straps and buckle to the BOA. Even though the Sidi's are "inferior" if you look at weight, stiffness etc... they win out in terms of comfort and fit to my feet making them the better shoe even though they are cheaper as well!
