I am a huge DoT fan and have had both spinners.
My first control panel had the Blackhawk. It is a serious piece of solid hardware. It has very good spinning momentum. Occasionally, though you could hear a little metal on metal while spinning, but spinning seemed unaffected. The springs on mine were really tight which sometimes made it difficult to move up and down, however, it was readily adjustable. Mounting was relatively easy as long as you have really long and skinny drivers. The only bad thing I can say about it is it is huge. It will take up some serious control panel real estate beneath your panel.
When I built my second control panel, I did not have the room my first one had. So, I went with the TurboTwist High-Low. It unit is very compact and despite being small the spin action seems fine (at least for DoT). The Hi-Lo feature doesn't have much throw. I have accidentally changed DoT targeting levels while using this, unlike the Apache. Since the unit is self contained, there is not a way to tweak this over time, which worries as springs start to wear. Mounting this spinner is a nightmare. You just can't use a spade or hole saw. The mounting hole is circular with three circular nubs cut out of it. I did a rough cut with a jigsaw and lot of filing and sanding to make sure that I did not mess it up. Also, depending on your taste, you may want to route it flush, which adds more complication to the mounting.
As for the spinning knobs, I like the look of TT Hi-Lo's better because it is polished, rounded, and has the concentric rings on it. Just wish it came in colors. The Apache is far less polished, had some nice grooves on it for better accuracy and came in red or blue.
As for performance, the highest score I ever made on Discs of Tron with the Apache was 112,000. While, just recently, I broke 151,000 with the Turbo Twist Hi-Lo. Now, I had learned some tricks and gained some experience between the usage of the two spinners which could account for the difference. I just wanted to let you know that if your scores on DoT are not near these, then it may not matter to you as both products are acceptable.
IMHO, if you have the room for the Apache, go with it. If you are limited on space, the TT Hi-Lo will work as well.
