So which Wife/Husband would you pick, and why?

I'm just curious who is the most popular choice for a significant other. Let know who you would pick, and a little information on why. I'm looking for other reason beside "OMG Riven's booty so good, wifu ez choice."

Mine would have to be Lissandra. I mean yes she is old, and timeless but I bet she is pretty under that head mask, and could bestow immortality. I mean I would have the chance to become a IMMORTAL King and possibly rule the world one day after freezing it of course, and have all the graggy ice I could drink. I wonder what her personalty is like under neath all that ice.

What about you, and why? Rioter feel free to add in.
