The MacBook Pro 16in has been one of my best Mac and MacBooks I have owned. Great keyboard, fast graphics, fast processsor, run great not a single problem with it and I have owned it from day one. I would recomend this machine to anyone needed a new computer. I have a Razer GPU and a AMD Vega 64 card. Going to upgrade the video card to the super duper AMD video card coming in the fall. that is what is great, you can upgrade the graphics card with a EGPU to keep the machine pretty current for many years.
Buy one you will love it.
Get in the real world. Most people don't drop £2000-£4000+ on a new computer. Even if they did, they'd want a proper GPU instead of that AMD rubbish.
