I've started half-way through Christmas break.

I'm seen all of Christopher Eccleston and David Tenant so far, finished 2 seasons of Matt Smith (still on the 3rd) and saw "The Ark in Space" of Tom Baker so far, and this is in a months time now.

At the moment, my favourite Doctor is Matt Smith (Though Tom Baker is also amazing, and might surpass Matt Smith once I watch more of Tom Baker).
Favourite Companions (As in those who have traveled) in order from most to least...

Captain Jack, Bernard (Donna's Grandad), Donna, Rory, Amy, Mickey, Sarah, Martha, Rose.

(Edit: Forgot Mickey & Bernard... derp :/)
->Not sure if Bernard really counts, but he traveled with the Doctor during the whole "Return of the Time Lords" episodes, which is long enough in my mind for him to make the list at least.

^I can't include Harry from Tom Baker yet since I've only seen a small part of him so far. 
While Sarah I got to see many bonus appearances during David Tenant's seasons.

If River can be added to the list (Even though, at least as I've seen she hasn't really traveled 'with' him yet outside of the "Let's kill Hitler" part) she would be second, right behind Captain Jack.

As for incoherence and bland female companions?
I can see that. I haven't really seen enough of the old yet to spot many Incoherence's yet though.
And female companions complaint I can understand a lot as far as Donna, Martha and (Especially) Rose are concerned. 
Amy I can't say so much for (But granted I'm still at the point in the show where she is travelling with him).

As for Matt Smith kissing... I haven't noticed it, unless if you even the cheek kissing.
If that, he does that with everyone male or female and in several countries and cultures (Mainly Europeans in my experience) that's just a common greeting.
