This is directed more towards players at around my rank or about 100-200k lower (so top 700K or better).
Notes on the choices, or at least my interpretations:
Never - I will never ever go for SS's. Either I think they're stupid or annoying to grind for, or I only care about S-ranks/FCs.
Maybe 1-2* maps - I only care to SS the easier difficulties, whether no-mod or with any combination up to 4-mod. Trying to SS anything higher is more trouble than it's worth.
Only my favorites - If I really really like the song, or have a really good feel for the rhythm of the song, I'll go for an SS. Otherwise, I won't bother.
Sometimes - I'll try to get an SS every so often, but only occasionally. I might even get lucky with one, but I'm not actively attempting them
Usually - I try to go for SS's about 50-60% of the time.
Frequently - I always at least attempt to SS songs whenever I play or grind them. However, I can settle for having some A/S ranks if I'm just not able to get that perfect accuracy.
Whenever I can - I always go for SS ranks, but unlike SS or nothing I'm okay with having non-SS ranks in my top plays (or plays in general)
SS or Nothing - Every play must be an attempt at an SS play, and I will not complete a song unless I get an SS. If I accidentally complete a song without an SS, I will attempt to make it an SS play whenever possible/when my skill catches up to the difficulty.
As a couple of follow-up questions:
1.) Why did you pick the option you did?
2.) Which option would you recommend to other players, whether they're veterans or complete newbies?
for me:
1.) I see the best possible play on any one song as an SS (or Silver SS, technically), so I want to strive for that whenever possible. I do sometimes accidentally let songs finish without 100% accuracy (usually when I don't spot the ending coming in time to quick restart or hit escape), but I always work toward SS-ing that song so I keep 100% accuracy. It just makes logical sense to me that you should be aiming for this rank whenever possibl.
Although, I also understand that when you're improving you can't always reach that rank at your current skill and have to reach a higher difficulty rating before coming back to an easier rating to SS those. I personally just want to go for SS's only so my skill is kinda capped at what I can SS.
2.) I would honestly not recommend complete newbies (whether to rhythm games in general or Osu in particular) go for SS ranks at the start. What's more important at that stage is getting a feel for the game, enjoying playing along to songs you like, and learning the fundamentals of the game. I already have a decade of playing rhythm games before Osu (Guitar Hero/Rock Band), so even when I first started I had enough experience to start going for SS's right away, but not everyone is the same way. I'd say if they're playing in the mid to upper 2* range, I'd suggest going for SS ranks.
For people who can competently play between about the 4*-7* range (regardless of what mods you use, if any), I know it's kinda your personal preference as to whether or not you go for SS's or S's or just high acc plays, but it just makes more sense to aim for the highest accuracy possible. It's a rhythm game. YOu're kinda supposed to go for what denotes the best possible adherence to the game's highest-rated accuracy metric: For Stepmania, it's Marvelous; for GH/RB, it's 100% FCs; and for Osu, it's 100% accuracy SS ranks. This applies to any mod combination or using no mods at all, although personally I completely understand if nobody wants to go for SS ranks with the FL mod.
Once you start getting into upper 7* ranks and higher where some songs don't even have FC's yet, then I understand not going super hard for SS ranks. You kinda need to have FC's first as a stepping stone (unless you're rrtyui playing The Big Black, then you skip that step entirely and go straight to an SS rank), maybe just to prove the song is FC-able in the first place. I mean, maybe if the best 100-200 plays of a song at this level have S-rank FCs, then there could maybe be some push to go for an SS rank, but that's about it.
