It's a personal decision. Both systems have their benefits and cost the same. For me, as a professional focus puller, the Light Ranger reduced my focus pulling instincts to a playing a video game. Just keep the green bars over the subject. Besides keeping shots sharp, our main duty is to help tell the story. For me, the LR is too distracting to do that. The Cine RT is a brilliant tool that takes the Cinetape to a whole new level of performance. I really like using it and I much prefer it over the LR. The Cine RT is way more simple to set up and is way less fussy than the LR even though the most obvious difference is the Cine RT does not have auto focus. That's fine by me! The biggest difference between the CRT and the Cinetape is that it's wireless and does not have a clumsy display to have to find a place for on the camera. The display/control unit is next to you and you can change settings at will - even when you're rolling. Anyway, the Cine RT works great for me. I hope this helps you with your decision!
