I have never used that one in the link, nor any other hang on stand. BUT as I look at the pcture, it looks like the climbing step come right up in front, meaning you would have to step aside after getting to the top, lowering the fold-up seat, then swivel-step over to the stand. All the guys I've seen using climbing sticks and hanging stands put the sticks a little to one side to make it easier to transition from steps to stand.
I hunt with a friend who uses a hang-on stand and sticks. They are VERY movable. He takes his in with him every time he goes hunting, then takes them back out (public land). He straps on the sticks, climbs up and hangs the stand, hooks a rope on his bow, climbs up into the stand and is ready to hunt in less than 10 minutes.
That's the nice thing about this set-up - you are very verstile. If you have hunted in the morning, then come back in the evening and the wind's a different direction, just go set up in that other tree (that you've already scouted) and you'regood to go. I'd say this is better for younger guys than us older guys. Just MHO.
Again - if you're on a budget and have time, and are hunting private land - I'd still go with a couple of ladder stands.
