When it has the same chip as my Macbook and costs more than a Macbook, it's gonna get compared to a Macbook.
Yes, you can compare it, but there are many more variables (cameras, screen, form factor...). I don't understand this trend of "it has an M2 so it must be like a Mac".
Strongly disagree, because with an iPad you're still locked to Safari, while on a Mac you can use any web engine, as well as plugins to make your web browsing a lot better, like being able to install UBlock Origin so you're not bombarded with intrusive ads like you are on iPad.
You would rather pay more for the worse experience. Please tell me how that makes sense
Very few people care about web engines. I can see it's relevant for you, but if Apple puts in a balance the benefits vs problems of enforcing WebKit, I think the decision is clear. About adblockers, to be honest, I've never had any problem without one, but you have many extensions if you need it. I will summarize why I prefer to browse (and more stuff) on the iPad in the next point.
And don't come to me like "it's a different form factor" when the iPad has been having an identity crisis trying to be a laptop replacement for years now. Just because it uses a touch screen doesn't instantly make it better when the overall software experience is objectively worse. And it's not just software, but hardware too. iPad hardware has also taken a downward spiral. Battery life has gotten worse even on the iPad Pros compared to the Macbook lineup that has x3 the battery life, the iPad has now had the headphone jack cut while the Mac still has it, hell vanilla iPads have a purposefully gimped USB-C port with slower transfer speeds because Apple.
It is really hard to justify getting anything other than a vanilla iPad anymore with how much worse iPads have become, and if you want proof of this just look at the quarterly financial reports. The Mac is making more revenue than the iPad quarter after quarter and the revenue gap has been growing larger. And once consumer model Apple Vision arrives, it's gonna get even worse for the iPad.
The iPad can* be a laptop replacement. Just like the iPhone can* also be a laptop replacement. And it doesn't need to be black or white; I prefer to do maybe 70% of my tasks on the iPad, and 30% on the Mac.
It's about both the form factor AND the software. It's completely subjective, but to me iPadOS is much more enjoyable and well-designed (from a functional point of view) than macOS: input is much more direct (i.e. no Menu bar), navigation is more intuitive, etc. And regarding form factor, I like how truly versatile it is: no matter if you're using it with the MK, without it, with pencil... the UI stays the same, you're not taken to a completely different mode (like with DeX). You can use Stage Manager in any format, whether it's with touch or mouse input. All that requires a lot of thoughtfulness.
But what baffles me is to read that "overall software experience is objectively worse". I can put myself in the shoes of those who prefer the macOS overall experience, is it so hard to see why millions of people prefer iPadOS? I think the fact that you're talking about the headphone jack or browser engines, while legitimate complains, explains why Apple usually gets priorities for 99% of the users better.
I think the iPad has done much better than the Mac in quarterly reports. Even with no models this year (!!!), it has outperformed the Mac 2 out of the 4 quarters. Taking a bigger picture: the iPad has performed better than the Mac since the pandemic, even if the Mac has received a complete overhaul with Apple Silicon. So this year we could see the iPad consistently surpass Mac's revenue.
The iPad has its downsides (as you mentioned, when it comes to battery, my MBP lasts way longer), but I enjoy using it much more than my Mac, so I'm not going to look for an equivalent-priced Mac when buying my next iPad.
