I haven't read the responses yet, but I'm sure you'll hear a wide variety of opinions.
I've had a Rowenta at my home and another at my studio since 2000, and love them both. No problems, no leaks, both just wonderful. FWIW, I haven't dropped either of them, I use regular tap water like the instructions recommend, and I clean them regularly (although only about half as often as recommended.)
Black and Decker has been a popular brand here. I've had two and they both leaked from the day after the warranty ran out. Neither got very hot. I still have the last one -- every time I think I should put it up on freecycle, I feel pangs of guilt about inflicting such an awful iron on someone! LOL
