I own multiple Harris, multiple Atlas, an LRA F-class and a Ckye-pod.
For field/PRS shooting, I love the ckye-pod. Very cleverly designed and well built. Big range of motion, can go super low to way higher then any of the other bipods, which can be accomplished through a combination of leg width and leg extension adjustments. Leg adjustments are fairly rapid, and I like the touch of having grip tape on the legs. Pan and cant features are not changeable on the fly - rather you set it once to your desired tension level with an allen wrench and shoot from there - which for me I personally like, but could be a downside to others. Option of ARCA/RRS or picatinny mount. There's a bonus barricade stop built into the bipod which you may or may not find useful, but certainly doesn't hurt to have. The feet are talons and are of good quality, have shot off of multiple surfaces including concrete with no issues. It's an expensive bipod, but the features and build quality are more then worthy of the price. If you shoot mostly on a square range, it may be hard to justify the price as all the features will not of much benefit, but this bipod really shines for field work.
I like the Atlas design and they have great customer support. Kasey and his team is awesome. I have the older versions with the wheel tension knob for cant, and I've found that the tension loosens up a lot over time, to the point that it can be difficult to get the proper tension on the bipod if it's too worn out. Of course, Atlas will take care of you in that case. The new CAL version looks really nice, and would be the way to go
The Harris' have a poor value proposition, as you have to pump a bunch of money into them to make them more versatile for our sport. Aftermarket mounting components if you want to go picatinny or ARCA/RRS (some are pretty weak and can fail), aftermarket leg extensions, feet, and even if you pump a bunch of money into them, you still at the end of the day have a mediocre quality bipod with stamped metal legs and very minimal adjustments.
No experience with the TBAC bipod. Seems like a well made and thought out bipod, but it's not going to replace my Ckye-pod.
