It's like the whole "what was first, the chicken or the egg" thing ... I think that Lorelai belongs with someone who is more like her and still not the same, like Chris. Luke and her just don't have that much in common ... it's always good in a relationship not to be like the other cause "you are supposed to complete the other", but Luke never really got her jokes and stuff. He is not into the stuff she is into ... he tried, I know, but it's not about trying.
About the tv ... well, that's just normal and very typical for guys ... we had that exact same scene here in january

... my husband won by the way

and now I really like that tv.
I voted for Chris and Luke, I mean, I would prolly pick them anyways, but from lorelais veiw, Christopher owes her big time for raising rory and he should be there for her now kuz he wasnt earlier, but luke has always been there for her.
wll, about that it is said and Lorelai wrote it in the letter too, that Luke was like a dad to Rory, but when you watch the seasons begining to end, from season 1 ... you will realize that it's untrue. They barely knew eachother in season 1 and in season 2 Rory tells Lorelai something about knowing Luke for 2 years ... so ... she was already 14 / 15 then. Like a dad ? The whole "he gave me all those that wacky / sweet presents" now in season 7 is not making sense.
The writers are writing themselves into the out ... they don't know the story by heart. There is a lot to interpret, but Rory and Lorelai both say that they only know Luke for like 2 years from there ... the whole horoscope thing is not adding up as well.
But it's a show ... we shouldn't forget that

.
I aagree though ... Chris should and has to be there ... for Rory and for Lorelai too, he is her dad and he wasn't there like he should have been when she was growing up ... and he should be there for Lorelai too. They were more then "just" soulmates ... they were friends from early age on.
I hope we will see more of him again, after the bitterness and the sadness between him and Lorelai is gone.
To the question "who should Lorlelai be with" at the moment I gotta say that I think she should be alone for a long, long time and find out what she really wants and then let love come to her ... she never really and fully appreciated any guy she was with and if she can't do that, she will never be happy and we will always see her running away.
