Buying a trailer-Leaf or Torsion Bar?

[Mr Pops]

Hey folks, I'm in the market for a tilt deck car hauler trailer, probably 18'-22'.
Whats better for trailer suspension, leaf springs or torsion bar? I plan on using the trailer to haul cars and pickup trucks and also to haul water for my acreage with a water tank that weighs just under 3000lbs loaded.
I've been told that leaf springs are cheaper and easier to replace, but also easily bent if you turn the trailer too sharp while backing with a load.
I want a tilt deck for better approach angles for loading small cars and also to aid in dumping water. Is there a type of tilt deck I should watch out for?
Thanks for any info!
