Well, seeing how the topic is still "Playstyles" until we can figure out a new one to discuss according to what I've read around here (though we should work on MU and stage discussion soon), let's see what I can do, and Kuro did tell me to contribute here, so yea, let's see what I can do.
For my style, I consider myself a hybrid between Defensive and Technical, with a bit of Offense in certain cases. Here's a tricky part.
While I, for the majority love playing the defensive, and prefer to be at a distance, provided that it's appropriate for the Matchup and if I'm not panicking if I'm not in the lead, I do like to change my style out of the blue and try being a bit aggressive while studying the opponent's habits and actions. Here's how it works:
Defense: My defense is well-known to many who has played against me, especially those who spar with me. Against certain characters, mainly those we can camp against, I sometimes wait for them to approach, and probably lunge out for a quick offensive attack, to surprise them. My defensive capabilities also include my little ledge camping game with arrows, mirror shield, sometimes AR, F-air or B-air back on the stage. This works well against some stressed out opponents that try to rush in, especially if I'm in the lead.
I can also be defensive to lure in certain characters in for a CG (like DK), or do the classic F-throw > Stutterstep F-smash thing if possible. Because those actions may require the opponent to be at 0%, I try firing arrows sparingly, sometimes making them miss on purpose to lure them in. There are times where I'll actually just stay put while crouching, waiting to see the opponent's next move, and possibly strike whenever ready. It can include an arrow when I see an opening, an appropriate close-ranged attack if close by, or even turn aggressive in an instant.
Offense: Switching to offense can surprise some opponents who are very well used to my defensive nature. This includes me slowly closing in while throwing out SH N-airs, F-airs, or arrows, maybe even SH U-air depending on the opponent.
For the CG or F-throw > F-smash thing, I may temporarily become offensive, just going in hoping to deal damage quick. If I do or don't I can switch to defense to get a better position.
Technical: This style is different, for not only can I incorporate it into both defensive and offensive styles, but it actually adds on to them to help trick the opponents. Platform canceling on SV and Lylat, the looping arrow stuff, Pivot arrows/grabs, using Up-B to platform cancel on some stages like PS1, and most noted, BF. Heck, even Wingdash instead of the BF platform cancel to trick opponents. As for multiple-arrow usage, it's one of those risk/reward type of things. I wouldn't expect to do this on every level though.
One of my goals is to trick opponents, or keep them thinking at times as I study their style and actions, and being technical helps, provided I'm on a suitable stage. Where defense usually gives me more time to study and adapt, Offense helps me study what they may do when they're possibly under pressure, and try to exploit them. Add that with being able to exploit basic weaknesses for certain characters (Camping and CGing against like DK, keeping Zelda above you, etc.). Each style helps, but even I can be troubled, and be blindly offensive or defensive if I'm failing.
For like Sonic, provided if I'm in the lead, I can just wait for them, shoot an arrow once in a while, wait for them, see what they do, counter if they do what I want em to do. I may even pivot grab their spindash sometimes to add to suppressing them, though I regret not knowing when they'll grab me instead.
For certain characters like TL, you may notice that they like to jump a lot, so I may aim arrows upward very often.
For those you can camp, like DK, Ike, and Ganon I just be defensive for so long that I can surprise em and be aggressive in an instant, and see what they may do to adapt if they can.
Another goal is to be a unique Pit. Some players may expect a common defensive Pit, or offensive one, maybe a "blind" tech one, but I like to mix it up, keep them guessing and such (platform canceling on SV has helped me a lot here), pressure whenever possible.
However, not everything is successful. I do panic myself against certain opponents and characters, either because I do not know some matchups, or am pressured enough to not being able to study or adapt quick enough.
Sometimes, playing against me can help with my explanation, and characters + styles do matter.
