Winters? Love it.
The polar night is eerily beautiful; much of it isn't pitch black, but rather blue-ish, thanks to refraction in the atmosphere - we get lots and lots of twilight hours!
Also, there is something soothing (to this guy, anyway) about the relative quiet outside - snow mutes much noise, birds don't chirp as much, most people spend more time indoors...
Summer? Well, at times it is convenient to have, say, a barbecue at two AM while working on your tan - but mostly I've found the midnight sun to be an annoyance more than a bonus.
(Full disclosure - I am not born and raised in the Arctic, I just sort of stumbled into a couple of summers and winter seasons in various places up north (from 68 to 79 degrees latitude); the locals are overwhelmingly in favour of summer!)
Winters are cold, but except for that it is nice to see the difference in light from day to day this time of year
Pretty weird when taking summer holidays in southern Europe, and it gets dark like 8 or so in the evening.

There are ofcourse a number of pictures - but one place to start for the curious is this group with (mostly) amateur photos from Troms in Norway:

I've recently moved back to Tromsø - and the light is still just as fascinating.
