No it is not:
IPv4 header: https://upload.wikimedia.org/wikipedia/commons/thumb/6/60/IP...
IPv6 header: https://bitjunkie.org/wp-content/uploads/2023/10/ipv6-Header...
Notice how the IPv6 header is simpler? That’s because it is. It has normal working semantics, got rid of fragmentation, TTL is replaced by hop limit, and link-local addresses actually work as intended. The addresses look scary != more complicated. Please stop perpetuating this myth.
If IPv6 were just an improved header and a longer address I'd be perfectly happy with it. I wasn't discussing either point you raised.
