I agree with Derek, but here are a couple of extra points.
The large machined frog support is a huge advance compared to the small badly machined support in later Bailey planes.
For a beginner, fixing the frog of a bailey can be a task requiring many repeats.
The relative lack of available frog twist in the bedrock is a great advantage.

This is often brought up (the fact that later frogs have small bearing surface that isn't precision machined). I have had to fix (and wouldn't have had to, but thought I did) one frog that was out of square in about 50 or 75 stanley planes (it was a newer plane with plastic handles). I also had one plane somewhere around type 18 or so that had a speck of slag on the frog that caused the iron to be suspended above the frog (and whoever had used it a significant amount, apparently was never bothered by it. I filed it off).
While the later stanley frog types may be unsightly, I've never seen any performance difference between them and the older frogs (and usually, they are in better order due to being newer and with less use). The iron with the cap set only touches two or three tiny contact areas on a frog - the machined nature of the frogs was a waste of money.
The only thing that really become unserviceable on stanley planes of later types (up to type 20 at least) is the round top irons - soft and junky and short lived when smoothing. But even for jack and jointer work, they're fine. If someone thinks they're not, they're fiddling with tiny shavings which is a waste of time and a display of relative incompetence in terms of work rate (even on fine work).
The large wheel adjuster on the later planes is an actual bonafide improvement over the early adjusters, though, as long as the threaded area is clean.
Somewhere along the line, we got sucked into this idea that stanley's later planes came up short as planes because people forgot how to set up the cap iron and use them the way they were designed to be used. Thick irons and lapping frogs, etc, is OK if you want to turn the planes into some sort of infill repro, but the plane can't be used in context as well and a productively as the original setup would've been capable of just by cleaning up the cap iron mating surface, lapping the sole briefly and checking to see that the screws are all tight (and, of course, setting the cap).
If I'd had fewer stanley planes in the past, I'd have less confidence saying that, but the two sweetest planes I've had (of stanley's manufacture) were a later jointer with the belt sanded frog and a blue stanley 4 type 20 (though I did replace the iron on that one, but with one of my own make and not with a rubbery or overly thick iron - I do have those on hand, but they're not an improvement once a plane is set properly).
