It’s more like a fair assessment of different tools, with pros and cons on both sides, and a fairly large amount of OSM-tasks where both serve fine.
As for presets, in JOSM many presets have been built into the selection panel, eg if you select a water object you can click the preset link above the selection, and things like intermittent or the kind of water body can be checked or picked from a list.
I agree that the learning curve for JOSM is steeper than iD, but once you get to want more, iD also needs some digging into.
Working with relations has been vastly improved in iD, but when it comes to e.g. international route relations with variants, divisions, sections using other complicated hierarchical route relations as members, there is no way you can manage that with iD. JOSM has better tools for that, although a tool like Knooppuntnet Monitor shows how route relation management can be improved further.
