I found the second gen pencil to be lot better and so the consideration of iPad Pro 11'
It's up to you but based on what I saw/read the actual experience while typing has not changed with the new Pencil. It seems the same. What has changed is the way it's charged, the size and it improved the storage. Granted those are good things, but obviously they don't just come with the price of the pencil, but also with the new iPad Pro. While the improvements are great I don't think that they are worth that much.
Honestly I think that the Ipad Pro might be too powerful for something that you will use only for notes taking. Now if you plan to take advantage of the device fully then yes it makes sense. I am just not sure that it's worth paying that much if you will use it only for taking notes.
The plus (for me) of the Surface line is that you can feel it as a computer. You can install full Windows apps on it, you can hook a keyboard to it and you will have the true laptop experience. Also the kickstand. While small detail for me that makes a difference.
I don't have it and at the time I bought the iPad I have (regular, 2018, 6th gen) the prices of the Surface Pro line were too high for what I needed. I already have a powerful laptop so it did not make sense to pay that much for another one. If I have to choose between the powerful Surface line and new iPad Pro, I choose the Surface line. Windows experience is way better than iOS for what I need. This way I can have tablet (for digital notebook) but I would also have a laptop experience whenever I need it.
Microsoft Surface Pen is the same price as Apple pencil, attaches magnetically to the tablet (and while the new Apple pencil does that, it's more expensive than the Surface Pen) and has a battery that would last you an year. Apple pencil might be better for drawing, but IMO when it comes to writing down stuff both pens work out great.
