I had some Elixirs back in the day. They weren't noisy and they stopped okay, but they were always spongy, no matter how much bleeding. Switched to Shimano after that and haven't looked back. I wanted to try Sram again, but the swelling piston thing kind of turned me off. I've had a set of Deore, whatever is a step below Deore, two sets of XTs and one set of SLX. I loved the XTs and SLXs with the finned Ice Tech pads. Then I found the Zee four piston brakes. I think they're the best value in brakes. I'm running them on my trail bike and on the front of my trials bike and they are magical. The Zee brakes still have the older style lever with the wider clamp. They don't flex as much as the newer Shimano levers with the skinny clamp. Shimano knew they had a problem because the very newest levers have a skinny clamp and a kickstand near the grip to stop flex. But to get four piston brakes with the kickstand levers is $$$ compared to the Zee.
