You are really asking "do you like Fords or Chevys" here and will come up with about the same type answers.
Systimax IMO is the best and of course will be the most expensive solution you can get. After that it will boil down to personal preference.
Something that i can give you is this. Regardless of what brand or brands you use, match the components. By this I mean if you are going with Cat 6, make sure all jacks, patch panels, cable, and patch cables are rated for at least Cat6. Then you will get what you paid for. Using any component less than the rating will result in less performance.
Hope this gives you some ideas.
