1. Nokia N9 - Been my primary phone for over 3 years now. On days I forget it at home and have to get by with a different phone, I can certainly tell the difference. There's still nothing that could quite replace it for me.

2. Nokia PureView 808 - I don't use it as a phone any more! Thanks to MS Symbian is fast dying. However, thanks to dedicated developers and community, there's still life in it and it's the best camera phone around, period.

3. Nokia X2 - Similar reasons already mentioned. I installed the Nokia Z Launcher, which is quite slick, keeps things clean without any distractions. Very well performing device. I must say I am quite impressed.
