This is how I did my slides. I used 1/4" HDPE corner trim on the along the two bottom sides. On my drawers I have one big drawer on the left and two smaller ones stacked on the right. I went with this approach because of low price, simplicity, and compactness of sliding mechanism.
The drawers fit snugly left to right in their slides, so no rattle. I don't have any latches - the tailgate when closed keeps the drawers closed. The tailgate and natural friction of the drawers on the slides keeps them from moving or making noise. When extended, the drawers don't sit on the tailgate at all - they are "wedged" between the top and the bottom of my overall housing, if that makes sense. You can't pull them all the way out with this configuration, but I've honestly never really felt the need to. They also just slide right out, so sometimes when I'm packing I will take them inside to pack and then just carry them outside and install fully loaded.
I really like not having any latches, and I also really like that you can pull the drawers out however far you want (1/2 way, 1/4 way, 3/4 way out, etc.), and they will just stay there, even if you are on a hill. I have a fridge slide that's on ball bearing slides and the fact that it just rolls around on even a slight incline drives me crazy. If you go ball bearing slides, get the 300 or 500 lb ones, and I would consider dual locking (both in and out) absolutely essential.
I would definitely use this approach again. The only reason I would use ball bearing slides in the future is if for some reason I needed 100% full extension of the drawer (e.g. for a pullout kitchen or something). The downside to these slides is that my heavier drawer (normally has 100 - 150lbs of stuff in it) takes a bit of oomph to pull out. It doesn't bother me, but if you had kids or smaller people who needed to get in there, ball bearing slides might be a better choice.
Here is a link to the corner trim I used. I used corner trim because it has a 90 degree internal corner, unlike the radius you would find on a piece of angle. This way I could make the square edge of the drawer fit tightly into the corner so no rattles.

Pros:
-simplicity
-cheap
-easy to implement and doesn't eat up 3/4" of width per slide like high capacity ball bearings
-easy to clean (just vacuum/wipe off). The grease on the ball bearings seems to attract dust.
Cons:
-harder to pull/push in out than ball bearings
-not 100% full extension
-i'm sure there are others but this is all I can think of at the moment
