The 735 is at least twice as good as either of the other two. It is an amazing stretch of patience for even a saint to run a thickness planer without a dust collector. The mess is tremendous. The 735 has a chip ejection fan that functions as a poor-man's dust collector. You have to buy the kit to get the hose and a filter bag, but you HAVE TO buy the kit or use a dust collector, or you can't use the planer. With the kit, you put a filter bag over the top of a garbage can, and the chip ejector blows all of your chips into the garbage can. Without the kit it will shoot a dangerous high-speed stream of dust and chips out the back of the machine. The other advantage of the chip fan is that you won't have chips getting caught on your drive rollers and denting your wood.

Second- it has a 3-knife cutter head. Short of a spiral cutter, that's about as good as it gets. More cuts equals smoother finished product. With sharp blades it will produce a surface that is almost indistinguishable from hand planing.

Like most professional planers, it has two speeds, one for dimensioning, and one for finishing.

I don't know if it planes down to 1/16" on its own, I think it only goes down to 1/8. If you have super straight-grained stock and feed it in the correct direction, you can run it on a sled and get down to 1/16" with sharp blades.

Also- very accurate height adjustment, with a chain drive. Comes with a magnetic setup jig that makes it simple to change the knives. Has a stock removal gauge, which I thought was cheezy, but I actually like it not what I'm used to it. Has depth stops, which are handy if you do something like forget to plane a board, or screw up some stock and need to get another piece- as long as you set up the depth stop when you do your original planing.

Don't like- it's super heavy. You need a cart.

I would also recommend getting the infeed/outfeed extension table set, especially if you're going to planing long 1/4" or smaller strips, or you'll get dreadful snipe.

It's the first "consumer" planer I've used, and it is almost as powerful as a low-end professional. You can take off 1/16" from a 12" wide board without bogging it down, but you probably can't take off more than that in one pass.

I've owned one for almost 5 years.
