The initial setup of the PC4212 is certainly fiddly and takes some test joints; but so does the panto router. Once it is dialed in for the particular thickness you're using; I find that I can cut as many joints as I want. I've never had a problem with the length of the boards, since I mount mine on a 36" bench and that is plenty for the drawer sides that I'm doing. With the panto router, you can't cut both sides of the joint at once, so you're going to need to get all your tails, then all your pins.

I don't deny that this is a nifty and versatile machine, I just don't think it is going to be better than the special purpose jigs. Thankfully, no one tells me what machines I can use, and no one tells you what machines you can use. Improving your own personal methodology for things over the course of different projects is half the fun.
