I wouldn't recommend sisters, as their army is expensive (all metal) and they're currently the most underpowered codex...A common phrase for Tau/Eldar players is "at least we're not sisters". Heh.
Also, in regards to your OP, SoB aren't female space marines, so it's not really all that trolly.
I don't see what you mean with Tau being a bandwagon?
My personal advice is to play whoever the fuck you want, ignore advice what other people give you (including me, if you like the sisters aesthetic/platstyle, go ahead m8), research on how each army plays, and pick an army based on lore/aethestics/playstyle.
If you don't like sacrificing units, Orks and Tyranids are out. If you want strategy, Spess Mahreens are out depending on who you ask.
....But then you go on to say no Xenos or Chaos.
At this point the only two options are sisters.
However, I urge you to do some research on the SoB playstyle/costs before you start a sisters army. They're fucking hard, -4 str and all that.
