I have a Max Nighthawk X9 myself, with MX Reds - it's a great keyboard and I'd highly recommend it. I personally love the reds, and would not go with a tactile key if you'll be using this for gaming... I'm sure you can imagine how annoying it might get to some people having your WASD keys 'click' every time you need to move forward, or to the left or right. I'm actually a computer engineering student, and typing on the MX Reds feels great, though I basically just pound on the poor thing until it bottoms out.
I like to compare the different mechanical keys to the SSD-vs-HDD debate... sure, they might be a bit different from keyboard to keyboard, but the improvement over a membrane keyboard of any kind is so massive that you'd probably be happy with any of them. I think the MX Red is a good all-around keyswitch, though, and would work quite well for your purposes.
Just my opinion. Take it for what it's worth!
EDIT:
Here's a bit of fanboyism towards my favorite peripheral:

...and something I tell ANYONE looking for a new keyboard or mouse: avoid gloss finishes. All of them. There's nothing worse than using your keyboard for a week and having it look absolutely filthy afterwards; a nice soft-touch or matte plastic (like on the X9) works wonders in this regard. Gloss plastic is an absolute fingerprint and dirt magnet, and while I'm sure a lot of Razer owners are irritated by my saying this, I avoid it like the plague.
