Which one should i buy first ?

You might want to ask over in the General Chatter board too since this is mostly a Custom figure area. Might get a few more replies even though Patraw's response is pretty spot on.

It's your money, you should buy whatever interests you the most. Ultimately, you're the one that has to be happy with your purchases.

That said, I'd go with Battlelord, but that's only because I like video games more than horror movies. However, I wouldn't pay the prices you quoted for either of those figures, but keep in mind that I'm also a notorious miser. There are a lot of relatively expensive auctions for those two figures on eBay, but take into account that they're also "buy it now" ones with zero bids (in other words, I wouldn't gauge the figures' value based on those prices).
