If you want scale speed and detail OTB (out of the box) than Tamiya is your choice. Lower hulls are usually metal, suspension is always metal, and the suspension is prototype, IOW Tigers and Panthers had torsion bar suspension, as does the model. Panzer 4 had external leaf springs, as does the Tamiya model. Wheels and idlers always have bushings, as opposed to Heng Long with just plastic on plastic. Most Tamiya tanks you can put bearings in the wheels with zero mods. Tiger 1 is not one of them, though. Wheels need a little easing out to take bearings.
The Tamiya builds an excellent runner from the kit, stock. There are of course many upgrades you CAN get, but with a Tiger 1, you need virtually nothing, unless you get in to competitions. Instructions are first rate, sound systems have the prototypical sound, IOW the Tigers 1 & 2 were recorded from the King Tiger at Samur Museum in France.
There are also many tricks to make the tanks run better, such as Dean's Plugs for the battery and motors, better motors, etc etc. Still and all, for a straight kit build, you can't go wrong with Tamiya. Of course, during the build you have to decide what paint scheme you want. Here's a couple samples of build up Tamiyas. And some of the detail you can go to, if you want to. Or, you can modify the tank to another model or time era, or like the Sherman, he's a captured German piece with the German 7.5cm, T 34 scrap as additional side armour, and German tool suite.
Me, I build fighters, not models. Even the Jagdtiger will be a fighter this summer.
