best to try some on first, whats good for you may not be for others.
This is very true, over the years I've owned various makes and have only just found a set that suits me perfectly.
Tried: (My personal cons)
Empire events - echo, foam
JT Flex 7 - to large for me, no quick change lens
Vforce profilers - single pain lens found it fogged
Dye I3 Pros - fogged and no quick change lens
Proto Axis Pro - these are my chosen gogs at the mo, perfect size, comfortable, quick change lense, not noticed my echo. Find it odd that these havent fogged on me yet the I3s did.
