I'll start: After switching to Neovide from the terminal for Neovim, I got really hooked on the animated cursor and smooth scrolling (links to Neovide's features page). It wasn't until 2 months ago when the earlier was added to Kitty. I did so much overthinking about which terminal to use, and realized that I wouldn't (and don't) use most of the features provided by ones like iTerm and Kitty, though I picked the later. I was pleasantly surprised to see it added, even if it could use more work to make long smooth cursor animations like Neovide. The only other feature I want is smooth scrolling, I can't believe there are no modern terminals with it.

(Somewhat) Side note: At this point many users realized that Ghostty got over-hyped, here is Mitchell Hashimoto's (dev of Ghostty) thoughts:

Ghostty: Reflecting on Reaching 1.0 – Mitchell Hashimoto

I didn't anticipate the hype. Some people think I am lying when I say this. I'm not. I'm not so naive to think that private betas and exclusive access don't generate hype in principle. But I didn't think many people at all would be interested in a terminal emulator. I thought I was building boring software for a niche audience. No hype!

But I was wrong, and the consequences were real. People were frustrated that they couldn't get in. People felt left out. People felt like I was being fake to generate hype. The waitlist grew larger than I was comfortable allowing in (given my prior stated priorities).

I'm sorry about that. All I can say is that I didn't intend for this to happen. I ramped up beta invites to try to get as many people in as I felt comfortable with (well, a bit beyond that). We ended the beta at around 5,000 users in a Discord of 28,000 at the time. Not quite the percentage of access I wanted for people but more than I could handle.
...

One more negative aspect of the hype is the expectation of Ghostty being revolutionary. It is and it isn't. Ghostty has different goals and tradeoffs than other terminals. For those looking for those properties, Ghostty is a breath of fresh air and does things that no other terminal does. But for others, it's just a terminal. And that's okay. I hope you find a terminal that works for you and I don't claim that Ghostty is the end all be all of terminals.

I looked up specifically examples of this and didn't find answers, they're buried in general discussions about why compiling may be better than pre-built. The reasons I found were control of flags and features, and optimizations for specific chips (like Intel AVX or ARM Neon), but to what degree do those apply today?

The only software I can tell benefits greatly from building from source, is ffmpeg since there are many non-free encoders decoders and upscalers that can be bundled, and performance varies a lot between devices due to which of them is supported by the CPU or GPU. For instance, Nvidia hardware encoders typically produce higher quality video for similar file sizes than ones from Intel AMD or Apple. Software encoders like x265 has optimizations for AVX and NEON (SIMD extensions for CPUs).

Personally I don't watch videos on software (except for skimming tutorials) since I prefer to learn about topics with written tutorials or Reddit. Software influencers have been on the rise for the past several years, everything from grifters claiming they can help you start an SWE career, to ones that make tutorials and showcases on software.

I'm more interested in hearing about the later. I came across found this discussion: What can we learn from Neovim’s rise in popularity? : emacs, with comments claiming that Youtubers like ThePrimeagen have helped a lot with making Neovim popular. I crossposted it to r/neovim and many so far many users there said that they found Neovim through ThePrimeagen's videos.
