Well, as interesting as another debate would be, I say both have their set-backs...the most obvious to me is the manufacturers gaurantee on the circuit breaker...they are all gauranteed to operate properly "1" time...after that , all bets are off...
On the other hand, fuses seem to beg to be over-sized by "handy men" all over the world !!!
So, what to do ?...put a lock on the panel and give the key to the closest "qualified personel"...as we all know, they never re-engineer anything !!!
