They’re generally interoperable, so it’s not a huge deal to use one or the other, though there’s presently more native client support for Lemmy. I use Interstellar on Android when I’m using a native client with PieFed.
I kind of think that it’s not a terrible idea to have an account on two different home instances anyway, just so that if one goes down for a while for some reason, you can still use the other to post with. With Reddit, if the thing was down, that was it (though to be fair, Reddit reliability has been much better in recent years than it was in the early years, when there were some pretty bad stretches).














I mean, there are basically no instances that have perfect uptime. Might be a technical problem on one’s end, the hosting provider having some issue, CloudFlare problem, someone DDoSing the home instance, buggy version of the software goes out the door and people update to it, but everyone has downtime at some point.
https://lestat.org/ (which doesn’t track all instances, but does let one sort by uptime) has one instance at 100% uptime and it’s only been up for less than two weeks, so…shrugs
