I like look of Frameless windows however I've read many times they are more prone to leaks or other failures. Also that dual-pane frameless have a higher failure rate due to the weight of the outer-glass hanging by the seal to the inner-glass and shear force over time causes a problem. Lastly that a cracked glass pane requires replacing the whole window in many cases. None of these are my personal experience just what I've read but they seemed to make sense to me.
