I'd say it depends on where you're driving, both on & off road - the anti-sway bar limits how far one front wheel can travel (up or down) without the other one moving - so it does limit suspension travel off road, but if you're not getting into situations where you're lifting a front wheel, removing it probably won't help much.
On the other hand - it also limits how much the vehicle leans in a turn and a fast "left-right" swerve that might be required in an evasive manouver on road could end up in disaster.
You could do as rascott suggested, disconnect it & tie it out of the way for a test drive - but - I'd say you're probably not going to test it in the scenario in which you're actually likely to need it - ever had to swerve to avoid something falling off a vehicle in front, maybe a kid darting into the street, a deer (or kangaroo) jumping out in front of you - or - ever tried to switch lanes on a free way at the same time as someone two lanes away?
Personally - if it's a daily driver - I wouldn't recommend it - but that's just based on my personal experience.
