The main benefit of having the router lifted by four chain driven shafts on each corner is obviously the lack of squint, but also that any wear over a few years is equal on each corner, that can't be said for a single post lift with sliders supposedly to support the other side, my own lift is able to be dial'd in to a silly exact amount 360deg rotation is 2mm in height adjustment on a calibrated scale, this is almost essential when rail and stile cutting with raised panels any slight out of depth alignment makes lots of extra work getting them smooth enough
A digital depth gauge is also an essential item, for checking the bits are the same height as previously if you change the production run during the day, making notes for each rail, stile and panel makes the job much easier next time.
As I said earlier, when using a properly set up purpose designed router table it becomes a pleasure to use instead of constantly having to adjust, bend down and kneel on the floor and move the lock switch (Triton) Lock the router height (most routers) when checking the router height from below the table most will change height when using the lock lever needing constant up and down adjustment (from under the table) to get the same reading as previously, I tried all the alternative shop made solutions and came to the conclusion that my life was ebbing away trying to achieve something on the cheap that can be solved by buying something purpose made that no longer took an age to fettle before I could start work, I know some will get a perverse pleasure from using something they made and keep adjusting, but that's not what I want from my woodworking, a well made piece of functional furniture is far more pleasurable.
