Btop is pretty and has good defaults for many things.
A performance monitor is not a good interface to strace, nor is it a good replacement for lsof, nn, arp, etc.
No, not really. To me it felt exactly the same (immature) way. That was a reason why I kept using htop instead. I feel the same about eg k9s, but there's nothing better to migrate off it.
The way I'm using it, somewhat customized from the defaults, showing some more, but mainly still showing the process-tree as the largest field...
... I navigate by either arrow-keys or mouse, mark the process, and apply another view of that process with one keypress, be it the default output of strace for that process, or the default of lsof applied to it.
Why should I have to type more than that, when that's enough in most cases?
The same would apply to netstat/ss for that process if htop would support that.
IMO that's a rather comfortable way around all the pids, p(s)kills and whatnot else.
Call me lazy, but after decades of *nix I really don't care anymore ;->
