I have experience with both. Hotchkis makes a great setup for a simple bolt on kit. The tuning is where they shine and the parts are well made. Hotchkis does not address suspension geometry flaws other than increasing caster settings which helps a lot.

Ride Tech goes a couple of steps further in fixing not only caster but offering tall spindles for improved camber gain. The tall spindles increase the already bad bump steer but they have a Tru-Turn kit for that. Fixing bump steer and using a firm feel steering box will vastly improve steering response & makes the car less twitchy/more precise, - more like a modern car. These fixes will really make your Camaro feel good to drive, it won't be pulled to one side when you hit a bump. It makes the car go exactly where you steer it.

In the rear suspension, the 4 link Ride Tech suspension reduces rear unsprung weight. You can feel the improvement in ride, even at low speeds. There is a handling improvement but it's not as large as the ride improvement in my opinion. Hotchkis makes a rear leaf that I like a lot but it's heavy so it isn't going to ride as well. It has a built in traction bar so wheel hop is usually not a problem, no extra traction devices are required. The advantage here is simple installation/factory appearance. A guy with a stock look Z/28 would want this combo.

Another option is the Ride Tech Street Grip package. It's more like a Hotchkis bolt on kit with lighter weight better riding fiberglass rear leaf springs. It's better riding than the Hotchkis kit, I think not as stiff.
