looking over at my big main workstation... i realise, despite several explorations* off to other states of existence, when the shit hit the fan, it's back to the vsido install with it. i have it doing some "mission critical" data recovery stuff at the moment. this is the first vsido i installed iirc [edit:
anyone care to remind me how long ago that was? i remember it was a january, but what year was it? when did vsido start?].

it has been through the wars. i have given it quite the kicking. any problems it has, came from me (~ not entirely true... some turbulence experienced with systemd's arrival).
i used stable n then testing branches for years. n then i started pinning the occassional thing from sid when i needed the latest (or at least newer). it got to a point where trying to pin what i needed was becoming more nuissance than the problems i was likely to incur by "just going sid".... and just going sid in my experience, as echoes VastOne's, was a refreshing surprise in the absense of the much trumped up pains sid was aleged to be riddled with.
and most of that was kinda just bald sid. i'd been on sid for a couple years or whatever before vsido showed me there are all those other tools n safeguards n further extremes n whatnots to help manage n mitigate n explore the sidness. ^_^
so, yeah, it's stable enough for sure, for >99% usecase i reckon.
just play it safe if your office is anything like a nuclear facility, or something the provides everyone with water or electricity, or risks catastrophe if the system chokes ever. nowhere too big to let fail. everywhere else, you can have reasonable confidence. but do try experience that for yourself. dont just take our word for it.
ps, arch bit me so many times, and not just small nibbles either. sid never bit me unless i was mistreating it. gentoo never bites, but seems to always want to be gumming at you. exherbo demands to be locked in a mutual perpetual bite. i've yet to have spent enough time with void to know if it will bite (though i presume it will). ... sid really is the friendliest roller.
* those explorations on that machine include: time spent with bedrock, which then had a sid client as the main glut of it, with my configs from vsido copied over
(so that was still basically running sid... just it simultaneously had the packages available to run from my arch n slackware n gentoo clients too); time spent in windows for elite dangerous, which then necessitated a radical hardware upgrade, effectively a new computer (case n peripherals were all that stayed same), and the same vsido install has picked up running again on that fine enough.
