You'd be surprised - possibly the difference in R&R'ing the nut or bolt quickly -or- spending half the day finding a work-around. There are many various types / styles of offset wrenches, some ratcheting. some where the offset is greater or more angled then 'average'.

I have a crazy looking offset, angled, dropped, box-end wrench designed for John Deere in-line diesels to remove the starter inside bolt. I bought it when I was in High school working part-time for the local JD dealer. I've had it ever since. I cannot tell you how many other times that I've needed that wrench to successfully remove fasteners.
