I haven't had one myself, but have used one and didn't like it, but that doesn't mean you won't.

Sometimes the corner is the best design solution. And you might like it just as much as I don't.

A lot of people get creeped out facing a corner, or just looking at the corner cut across on a diagonal. You lose floor space and sometimes cabinet space, when you cut across a corner. A cooktop is less trouble, but there's some extra fitting that needs to be done in a corner to make the oven on a range properly accessible. You have less easy in and out, side access space.

None of these are reasons not to do it if it fits better in the corner, or even if you just like it. They're just some of the reasons why people often prefer different solutions.

yes! It's all about what you have to work with. If I had a bigger space I would never choose it...but for me, with our footprint and budget it was right.

you have to be very precise in fitting the counters and cabs around it.
It is a little awkward step to the side to open the oven. I have a flat wall behind the range and a window on one side and open space on the other so I don't feel cramped..

They take a lot of wall space. The range will be deeper than standard cabinets, so be sure to take that into consideration when planning your cabinets on each side of the range.
