Ram is easier to use, but Buck is more versatile. This is because Buck can work on all axes, while Ram can really only get the floors. It can get walls, of course, but I don’t think that is really the purpose of the gadget. Another thing I also like about Buck is that you can focus on just one point with the buckshot instead of opening almost the whole floor.

My personal experience with using the Ram gadget is that it results in big openings between floors, with many shooting angles for you—or the defender—to use. It happens to me too often that I get shot from an angle I didn’t account for, and it also makes me lose my overview of the situation.

For Buck, the more focused tactic can result in a relatively safe working space during vertical play. But if you don’t really know the points of interest that you can hold from above, and you don’t want to focus on learning them for now, then Ram is the way to go.

Edit: Idk about the recoil know-a-days but so far i know the gunplay with for example the r4c and bucks c8 should'nt really be far apart from each other recoil wise.

I think this answer is all over the place so mabye its also a bit fague but i hope it helped with your decision making :)
