Do you have any preference as to what time of switches you want? Have checked out the difference between Reds, Blacks, Blues and so on?
If you don't care about macro keys, this is really the question to answer. If you're uncertain or don't have experience with each the best thing you can do is try to give a keyboard using each a feel; that not often being possible this comparison gives a decent idea of the major differences "TH Cherry MX key comparison"
In my opinion its 100% personal preference based on your typing/playing style. For $100 Cooler Master Trigger would be my choice (models with certain switches are as low as $102 on Amazon right now), but the TK is always $100 or less so you'll save yourself some hunting around. I've used every one of Cooler Master's mechanical switch keyboards (mostly Cherry MX Blue) and though I've had a few quality control type issues, their products are solid compared to most sub $200 options.
