The way I see it is, he's admitted to putting himself first in relationships in the past to build his business but has said he's ready to put more into a relationship now.
But jumping from him being number one in his own life to having a partner with a child would be too big a leap, so I think he'll choose Lana.
I can see the chemistry between him and Lana and while she might be more interesting they're both more equal in the relationship.
With Snez, it's like he ages a decade. He takes on a completely different persona and I get that. Different people bring out our different sides, but I also think he will tire of the responsibility, the distance travelling back and forth and coming second to little chicken. Which is proper order in the early days. She will have school and friends and family that I'm sure Snez wouldn't be taking her away from so soon.
It's down to the way each girl makes him feel isn't it.
And which one he knows he will be able to live with.
An equal or a daddy figure.
In saying all that I think he'd have more of a chance of it working out long term with Snez than with Lana.
