I went Smittybilt. They get a lot of flack on here. But for $250 shipped its tough to beat the price. The biggest negative you here is "fitting" issues or bolt holes not lining up.
I guess i was a lucky one in that mine bolted strait up and had no issues. I wonder if there was a time period of a bad "run" of em cause lately i haven't heard as many issues.
The ACE sliders are great! However you typically need the rubicon rails with them to make them truly functional, so if you don't already have those you'll be looking at a final total well over $500!
