I personally prefer the free standing oven, however I have been told that you can get food or spills in the gap whilst cooking and it is a PAIN to clean properly due to the small gaps.
Good luck!
I prefer its cook top layout and I like that the knobs arent on the top but you raise a good point maybe you can get it siliconed or something ?
Agreed, I reckon it's more ergonomic and aesthetically pleasing. No too sure about the silicone, in some homes I have seen the gap to be as big as 1cm wide and some looked liked they were press fitted in
