If you need a lot of weight to sink for whatever reason (thick neoprene, drysuit, etc.), I think the DUI weight harness is nice. I finally spent the money on it -- much more comfortable than a weight belt, though it seems pricey for what it is. Of course, putting the weight pockets on the backplate harness itself is nice since you don't have the extra buckle and shoulder straps of the separate weight harness --- but if you think you are ever going to need your setup to float without you in it, do the math and make sure it will if all the weight is on the backplate harness.
For strictly single tank diving, sometimes I think a jacket BC with built in trim and weight pockets is not such a bad option. Of course, it does take a lot longer to dry off than a metal plate and a wing, and the backplate and wing are more adaptable over the longer term. If you really, really get into diving, you will probably wind up with a backplate eventually anyway.
