My vote is cockerel.
This is one of those tricky EE's
Lots of girly and manly features to it. Yes, that comb is large but I have had pullets develop scary combs early on too. What concerns me is the feather shape and the red in the face. Pullets will get this red color when they are getting close to POL. At 9 weeks old it is very unlikely a pullet would be this red.
As far as the feathers go, I think if you start parting the juvenile feathers on the saddle area you are going to see a lot of pointy feathers growing in. In the shot where you have your 2 birds and you are aiming down at them--compare the feathering. The blue one has much pointier feathers and after they start juvenile molt in the next few weeks you are going to see a lot of major differences in feather shape between these 2 birds.
From experience, I have kept birds like this until I knew for sure. All of the ones that had pointy juvenile feathers always ended up being boys.
If I were you I'd hold on to it for a while longer. If it is a bird from your flock (or if you plan on breeding it) the extended observation will give you a lot of valuable information on the early sexual dimorphism of your birds. With your next hatch, you will have a benchmark to go off of.
Also, it is going to be a stunning bird with that lacing--I'd keep it just for eye candy!
