well ive always had Battle Version ones (think im putting in Ksports soon though), they do their job to hold the wheel where we set it. its been 5 years almost and they have been on there fine still. IF you are going to be really low, you might want to notch the subframes bottom collar so it doesnt connect with the toe arms (no matter what brand i think) at full suspension travel (bumps). it wont break but will bend them which means you'd have a change in alignment and might be more likely to break after bent too.
