I'm living at Penang. Have JEB for front door and THC for the rear. The JEB with 13 locks (with top lock) but not for the rear. My advice, avoid the one with the top lock as debris will come inside through the lock and could jammed your door from locking/unlocking.
Quality-wise, THC is better than JEB but only at the decoration/design part. Both of mine are with laser-cutted. The THC is slightly thicker than the JEB. For the frame and door, they are similar. I got mine at fair at PISA few months back.
Both doors are open inside. By default they are open outside and have to pay extra (RM150 each if I'm not mistaken). Front for good feng-shui but back to avoid blocking the road behind (the access road is for 'lori sampah' access). I read around from international pages, for public building, they are always open outside to cater for mob during emergency situation. For houses, we need open inside since the hinges are inside and thieves or robbers cannot get access. For open outside, the hinges are visible from outside and can be manipulated to detach the door (I think they have mechanism to avoid this).
From my survey, most locally produced doors have hinges which are visible whether they open inside or outside; whereas for Janus doors apparently , the hinges are concealed whether the doors open inside or open outside.I find that the security features in Janus doors are better.
