There are several. They always have good look, htc sense UI is great, beats audio good for music playback, some of them have playstation store certificate and of course, the camera department is good.
Their smartphones in general? Honestly, I hated the UI until they revamped it in the One. The new Sense UI looks a lot more streamlined, plus the all aluminum body is very pristine looking. I would still take Samsung/Nexus devices over HTC though.
