They all have their advantages. Some are easier to open/close one handed, some are better for ambidextrous use, some use less parts, some are stronger, some are less likely to release if used with gloved hands or with twisting forces. However, most all of them if properly executed will be more than strong enough for "normal" folder use. We almost never see lock failure posts unless the knife was abused till it failed. These days I'd bet the cost of manufacturing and licensing of a particular lock for most companies is a big deciding factor, and it's the reason the liner/frame lock is used so much. Few parts, cheap to manufacturer, and no licensing costs.
However, it's also by FAR the lock design we see the most complaints and issues with. We can't go a couple days without a post about a badly fit frame/liner lock from just about any company you can name no matter the price or amount of respect the brand has. The tolerances on perfectly fitting a liner/frame lock so that there is no lock rock, lock stick, blade retention, is anything but easy and companies have proven time and time again they hard time doing it consistently.
It's for that reason I prefer locks like the axis, compression, ball bearing etc. In my experience those designs are able to be mass produced with much more consistent results. There are more parts, but I see way less posts about those designs failing than poorly fit liner/frame locks.
