Surprisingly, given that it is Microsoft - I have had far fewer crashes on my Windows Phone than my wife has with her iPhone.I use an Iphone 6. I'm not a fan of apple products, but i like their phones because their software is solid. They rarely crash, as I seen people with android device complain about app glitches, phone freezes etc.
With other Apple products, this was long the claim. Not anymore. I have been using Macs for over 15 years now, and find them crashing quite a bit. I am glad, also, that Apple finally decided to include a button for ejecting discs - previously, if the computer didn't recognize that it even had a disc, your only resort was to insert a paperclip into the drive to trigger a manual eject.
