The Techangle's vibrate and beep. I have two and they are nice where you have the space to grab them in the right spot on the handle. They're also nice because they read torque in real time and will hold the max tq when you let off so you can watch to see if a fastener is starting to give, say over torquing head bolts. When it comes time to get in tight spots, I'd take the 1/2 beam click style. If you can't see the display, you can't see if it randomly decided to turn off, which happens. Other times it turns off because you grab it wrong and loosen the battery cap. Other times you grab it and hit a button, then have to cycle back to your setting. They're just a pain for cramped spaces.
Whatever you get, just make sure it has the flex head. That extra 15* is the difference between cussing and busted knuckles, or clearing that (dual cp3, turbo, bracket, master cylinder, etc.....) and moving on with your day.
