In reply to Stephenmuntuk:
With the exclusion of Crib goch, horseshoe etc, all the routes are pretty straight forward. Whilst I don't know what level of adventure you are after, I would guess you will find the Llanberis Path a little too straight forward.
I prefer the Pyg to the Miners as it's a more gradual climb, rather then flat for a while then suddenly quite steep. If there's no snow in Pen Y Pass, the Pyg might get you up to the snow line a little quicker.
Difficulty of the two routes is similar.
As long as you're not bambi with crampons and know how to use your axe then it really doesn't matter.
As mentioned, weather is the main concern.
