I personally don't like the look of those knife switches..... too much unprotected conductor for my liking.... and too much "throw dimension"
That's why I went with the screw top style. So far so good with them.
Just a personal opinion thing, no engineering basis for it.... I just like things somewhat neat and tidy.
I would have prefered the marine type disconnect (or industrial panel mount type, which are similar), but there's a significant cost differential there...
