Logic notation question

Hi fam and happy holidays to those celebrating!
I had a quick notation question if that's alright? So coming from a formal logic background and Powerscore tutoring, I was always told to notate an "and" statement like so:
..........B
A→ +
..........C
However, while I was foolproofing the Logic Games from PT 70 I came across J.Y's method/style:

A→B
↘ C

I do remember this notation from my 7 sage days years ago and more recently from some lessons upon my return, so I tried it. No surprise, it made the game infinitely easier (Game 2 for reference).

My question is this: Are there situations where one style is better than the other and if so what are they?

Thanks for your time!

    They're essentially the same thing, but I personally prefer 7sage's method because it's more visual to me and makes chaining a lot easier. I think it really comes down to what you think works best for you in terms of efficiency. Happy holidays!

    Really comes down to what you find easiest. I also took modal logic in university. I just use ampersands.

    1. A --> B & C
    2. A
      Therefore
    3. B&C (1,2)
    4. B (3)
    5. C (3)
