Here's one of the downsides of laminated irons.

I'd bet a pound to a penny that the iron in this Ebay listing is laminated. If you go to the very last photo and zoom in you can see the surface is cracked or crazed. I've seen that a few times, it's something to beware of.
Another problem can be that they're tricky to flatten off, not impossible, just more work than later irons. I've got a couple where the cap iron doesn't seat as well as I'd like, so at some settings you can get shavings wedging between the iron and cap iron. With a bit more effort I could probably get them fixed, but I'm not short of irons and life's brief enough without that on the to do list!
A final issue is that laminated irons are pretty
old, so finding examples with more than an inch of useful life left isn't all that easy.
With laminated irons it seems to be a case of when they're good they're very good; but when they're bad they're awful!
I had a look today at a pair of Bailey planes that I like and use regularly, a 4 1/2 Record and an 06 Sorby. Interestingly they both had laminated irons, I'd not realised it before but maybe I am favouring these irons.
I don't know how old this iron is, but it still looks like it's fresh from the wrapper. And as a practical, user, smoothing plane I'm not sure what else anyone could possibly want?
The I Sorby 06 is interesting, the iron is stamped I Sorby and it has the sharp angular top that's the chief characteristic of all the laminated irons I've seen,
I guess the iron is original to the plane, there's no doubt it's laminated, but as working planes I'm not grinding off the camber on these. There's a bit more surface corrosion, but judging by the amount of iron that's left it wasn't used all that much (or maybe the original owner swapped irons around?). I don't know if this plane was manufactured by Sorby or if it's a badged Record? Furthermore, I don't know if these irons were even made by the plane manufacturer, or were subbed out to a third party?
As with the Record, the results are pretty much everything you could want from a tool. Maybe a Lie Nielsen with an A2 iron would hold up better on highly abrasive timbers, I don't know because I've never tried them out side by side, but for most users that's a non issue as who works Teak and Rosewood these days? In any temperate zone hardwood it delivers exactly the shaving I'm looking for, and I'm not conscious of having to hone it any more (or less) frequently than a modern LN or Veritas iron.
