snake case...

I did it for years in Perl then moved to camel with Java. Now, I sort of like not having to type underscores.

I went the other way. I like it when my code doesn't look like a jumble of random letters with the least important words capitalized.

I went back and forth, both ways. I started out in Python with snake_case identifiers, then moved to Javascript with camelCase, and now I mostly use Rust with snake_case for names and UpperCamelCase for types.

I don't find either style better than the other, the only time I notice anything is when I switch between style conventions (e.g. switch between JS and Rust or C++), because I need to break the habit of typing one way rather than the other.

Still, I find readability of the two styles pretty much identical at all times once you get used to both.

I mostly find the readability the same, except for acronyms in the middle. RemoteHTTPIPAddr vs remote_http_ip_addr. I prefer the latter, but my go-to language these days encourages the former.

The "What is an acronym really and when should it be capitalised" debate is grey enough that it's easier to consistently use

RemoteHttpIpAddr

Not capitalizing the entire acronym is the convention in modern Java and C#.

I work in telecoms where there are so many acronyms that snakeCase is really painful (but we still use it). As for your second example, why not remote_HTTP_IP_addr ? Even more readable IMHO.
