I feel that Apple is doing the best they can given their current structure and given the resources at their disposal. It's not a question that can be answered with a simple yes or no.
What I feel is that people look at one aspect of Apple on its own, form their own opinions and then conclude that Apple is either winning or losing the plot because of it. The iPhone garnered 90+% of the phone profits! Airpods delayed! MBP delayed! Mac Pro possibly canceled! Apple is _______ because ________! None of us are wrong, but Apple too has its own long term plans and doesn't exist to serve any one of us in a vacuum either.
When I look at what Apple is doing in its entirety, I see a company who is slowly but surely gravitating towards what they believe will be the next big thing. The things we are criticizing Apple for, I feel they are simply growing pains as Apple prepares to leave older markets behind and enter new ones. And I feel we need to be understanding in this area.
Apple is rapidly growing its ecosystem (within such a short period of time, we have a new Apple TV, Apple Watch, airpods, Apple Music, revamped Siri, iMessage and iCloud photos). And the price to be paid for this is that Apple clearly has had to neglect the development of the Mac. One person might be willing to give this all up in exchange for a better Mac Pro. Others may not be so accommodating.
This doesn't mean that Apple is incompetent for neglecting the Mac, it just means that they made a conscious decision to prioritize the development of other aspects of the Apple ecosystem (such as iOS) which they felt were still in their infancy and so needed the attention more, over macOS and the Mac (which are, imo, pretty much mature and complete). In short, it's an informed decision, not one necessarily borne out of incompetence or hubris.
On a tangent regarding your point on bad decisions,
If it's one thing Steve Jobs brought to the organization, it was a healthy dose of "common sense". He somehow had a knack for being able to see what a product ought to look like at the end and guide people accordingly.
It's like someone coaching you on how to ride a bicycle vs you figuring it out yourself. Sure, without a coach, you probably might take longer, and maybe suffer more falls and injuries in the process, but in the end, you will still learn how to ride a bicycle, instructor or no instructor. So falling down and scrapping your knee might be a bad thing at that particular period in time, but when you consider that constitutes part of the whole learning process, maybe it's not such a bad thing after all when you look back at it in hindsight.
I don't think Apple is that much worse off with Steve. Yes, without a man like Steve Jobs telling Apple engineers what to do next, Apple will (and has) make more mistakes. And Apple will learn from those mistakes and become wiser for it. There are things that even a simpleton can teach a scholar, after all.
For example, watchOS 3 was essentially Apple rebooting the Apple Watch project after numerous false starts. Under Steve Jobs, the Apple Watch would probably have launched with the equivalent of watchOS 3 right from the start, saving Apple the hassle of having to redesign their software from scratch (which I am sure entailed no small amount of resources and manpower).
So in a sense, yes, it was a bad decision to release the original Apple Watch as is, but it's also part of the learning process. And ultimately, I feel that Apple will still end up at the same destination, with or without Steve Jobs. It might take longer without him, but Apple will still get there eventually.
I hope I am not babbling, but I find I can't really answer your question with a simple sentence.
