Thoughts on Daemonhunters builds?

I am just starting my second 40K force. Daemonhunters.
But what to do with them?
I have come up with 4 different builds and wondered what people think of each.

1) Pure DH. Inqs, Assassins and ISTs
2) Pure GK. Just Grey Knights and GK vehicles
3) GK + DH. Mainly Grey Knights with 1 Inq, Assassins and maybe 1 IST squad.
4) DH + GK Mainly Inq, Assassins, ISTs and a couple of GK units.

Thoughts, comments and ideas?

Thanks in advance

it depends the way you like to play
but for me : 2 and 3 will work fine

3 would be my favourite choice for the models.
Does 2 work well?

2 works well with vehicles (rhino rush style) and is somewhat difficult to play if not, because of the few models (and troops particularly) and because of the few anti-tank weapons but with tactics you can win even if it's not a top notch army (until the new hoped inquistion codex)

So maybe 2 with Landraiders?

1 LR and 1 LRC or LRR

Sounds like a nasty force. Even if the rules are abit old

Hmmm, my build is closest too number 4.

I'd say go with 1, you can take all the cool units in the book without feeling restricted.
(Well, except deamonhosts, but those are not that great anyway.)

I think i mat start with 2 and expand into 3

I personally use number 3 but sometimes number 2 as well.

I mainly use number 3 thought just because i love assasins!!

I havent played with Assassins yet but I love the models

I'd personally use the third option, because you still get loads of Grey Knights, but you also get the awesomeness of Assassins!

Number 4 is my kind of game.

A GK GM + retinue in a GK Redeemer
A couple of dreads,
An inquisitor with ISTs and assassins to make up the rest
