I'm not going to do a ton of plowing just some garden areas or food plots
The more bottoms a plow has the more difficult to adjust for good service. Plowing can take quite a while to learn as a skill. Unless you have a lot to plow, go with the two bottom, assuming the wear parts are serviceable.
A fourteen inch plow will create a furrow from 5" to 7" deep, laying over soil next to the furrow 5" to 7" high; total soil roughness 10" to 14". Is your top soil at least 7" deep? You do not want to mix top soil and sub-soil.
Plow wear parts are not generally available today but Dearborn and Massey-Ferguson plow parts are likely more available than others. 12" and 14" plow parts are out there, 16" very difficult to lay hands on.
Old trip plows generally have to be opened up, cleaned and lubricated before the trip mechanism will reset after tripping.
If you have Draft Control as well as Postion Control as part of your Three Point Hitch hydraulic system, the plow and tractor operator are reasonably well protected from underground obstructions. When adjusted properly, Draft Control will lift the plow automatically when it encounters an underground obstruction.
PICTURES: Ford Series 101 Trip Plow, 2-12", probably made by Oliver for Ford. Cleaned and lubricated once, has worked perfectly since, with annual greasing.
