Landyachtz are known for their downhill disciplined decks. Price should be in the medium range, about 120-180. Lots of their boards come with drops and w concave, which is good for locking your feet in during slides, pushing, etc. I'd go with these if you're looking into LDP, freeride, downhill.
Sector 9 has some nice and cheap boards, which is why it's the go to board for casual riders that is looking for light cruising, carving, commuting, etc. however, there is a line of boards called the "Downhill Division", which are pretty good boards for downhill/freeride. I personally have no experience with Arbor but I would assume it's pretty similar to Sector 9. I'd go with either of these brands if you just want a cheap but decent board.
Loaded, in my opinion is kind of overpriced. A lot of people like the nice flex they have, especial because you can choose accordingly to your weight. Just buying a deck though will cost you more than $200.
All in all, it's all going to be personal preference and what you're looking to do with the boards. I'd go to a local skate shop and try the boards in person, see if you like the feel of it, research more on silverfish or something. It's hard to give each of these brands a number rating because there are so many variables that affect your ride, such as the trucks you use, the wheels, bushings, etc..
