I’m not a Nano user, but I just tested it, and it appears that you can achieve the same result as "C-u M-! journalcl RET" in Emacs by pressing Ctrl-T and executing journalctl. In most scenarios, it truly does not make a significant difference whether you are working with text files directly or the output from journalctl(1). Any in many cases, analyzing logs with journalctl is significantly easier than with grep etc. Often times, you want to only read log entries from a particular service, in some specific time range, and that can be pretty difficult with text log files, rotated into multiple separate files. Compared to e.g. journalctl -u ssh --since="09:00:00" --until="17:00:00" --grep "invalid format" But yes, if you need to analyze journal files in a system that lacks the journalctl program, you're out of luck. I am certain there are numerous other disadvantages to binary journal files as well. There is a tradeoff in everything. Sometimes it makes sense to run rsystlog in addition to journald to get both log formats.
