Lots of good brakes out there. Decide on the features you want (tool-less or not, maximum recoil reduction vs less blast, integrated tuner vs just a brake etc) and narrow it down from there.
I've been happy with the EC tuner brakes on my smaller precision rifles, but I don't know if I'm getting any noticeable benefit for the extra money other than looks compared to the Spearhead or Heathen brake + tuner. That being said the EC tuner brake does look really good on the end of a barrel.
On my big rifles I've used the MPA 4 port and gen 3 APA fat b@stard brakes so far. The gen 3 APA brakes are absolutely awesome for recoil reduction on a magnum, and on long barrels the blast isn't terrible. A couple guys at the range were shocked at how tame my 338 Lapua was with that brake (285s at 2945fps).
Lots of options, really hard to go wrong.
