+1 on the Makita. Nothing against the Metabo, but I've had the opportunity to use the Makita several times, and if I had to lug a thickness planer to job sites, it's the one I'd want in the van.
The DeWalt 735 is a funny animal. I used to have one, upgraded with Shelix, Wixey gauge, etc... and it worked great when I was running my business out of a storage unit with 120V power from a generator, but I wouldn't want to heave it in- and out- of my van on a regular basis. It's a great solution if you want a garage-based machine and only have 120V power, but if you have access to 240V there are a lot of better options out there.
Perhaps some questions to ask yourself are:
-- Are you intending to take the machine on-site? (Portability) Or, are you just looking for something in the bench top class?
-- If you had to choose, would you prioritize surface finish or power? My memory is that the Makita delivered a better finish, but other machines had more power
Other reminders would include:
-- Remember that some of the machines marketing themselves as having a "segmented cutter head" are not necessarily set for a shearing cut (like a Shelix or others), rather they just have smaller cutters (sometimes steel, not carbide) that are still producing a "chopping" action, as opposed to a shear cut. Be sure to carefully inspect the cutter head if you're buying this type of cutter head so you know what you're buying.
-- Remember that nearly every planer on the market produces a finish which will require some amount of sanding prior to finishing.
