If you're thinking about it, it probably means you have the ability to afford it. I would get the 16".
If it's important to you, the 16" is hands and feet above the 15" in terms of processing power and graphics rendering performance! Drastic difference!
I won't even bother going through the other commonly known pros/cons about either machines.
Paying for extra space is what is throwing the price out of balance.
I bought a new 15"MBP in 2019, and don't regret it a single bit. However, If given the opportunity to get the 16", I would! I personally don't even care that much about the keyboard drama. All my Macs work fine for me. If something happens, that's what the warranty is for. Would be a different conversation if I had to deal with other company warranties that don't have in-person coverage.
Also, the 15" touchbar MBP is depreciating VERY quickly right now because of the 16". I wouldn't even think about buying a 15" new when they are only selling left over stock. Pick up one that is used and still under warranty. That's the only way I would choose the 15" right now over the 16". You save a TON of money, and it has already gone through great deal of depreciation.
