They both have their strengths. I use the iPad as my main device every day. The portability is great, note taking and sketching with the Pencil is great, reading PDFs and websites is great. Listening to podcasts in the background is great, music is adequate for many cases. However, there are other things for which the MacBook Pro is simply necessary.
My plan is to upgrade from the 1st gen 12.9" to the latest 12.9" (maybe the 11", I have to see them first) then next year I'll ditch the MBP and get an iMac 27". I almost never need to travel with the MBP any more. The iMac would be much better for the heavy lifting like Xcode and creating presentations and lab reports. Because of the file system I find that macOS is much better for archiving all sorts of things like scans of papers and receipts. The iPad will be a great accessory and the iMac will be the hub.
I find I'm not much of an iPhone user. I make phone calls and use iMessage and take some pictures and navigate with Maps. I find that at night I usually have around 80% battery remaining. I regularly drain the iPad.
