Nah. I just gave you the basics. This is the information a pro would provide you with.

To sum them up:
Reimu A: Homing shots, moves slowly, 3 bombs, extra reflex time, smallest Cherry point penalty for bombing
Reimu B: One of your best options. Strong, straightforward shot, moves slowly, 3 bombs, extra reflex time, smallest Cherry point penalty for bombing
Marisa A: The 'expert' option. Strongest shot, fast movement, 2 bombs, lower point-of-collection at MAX power, racks up Cherry points like crazy, but has the shortest reflex time, and huge penalties for bombing.
Marisa B: The 'Master Spark' type. Strong shot, fast movement, 2 very powerful bombs, lower point-of-collection at MAX power but doesn't get as much Cherrypoints as A, and has an enormous penalty for bombing.
Sakuya A: Homing shot, 4 bombs, larger grazing area, medium penalty for bombing
Sakuya B: The most eccentric type. You can aim your shots, and your bombs can be used very strategically for Supernatural Borders (most effective on Hard/Lunatic). Pretty powerful, 4 bombs, medium penalty, larger grazing area.

Generally, Reimu A (the one in red) and Sakuya A (the maid in blue) are the ones for beginners, since they have homing shots. Reimu A has the advantage of having a smaller hitbox, and she's a little easier to control, but her shots are the weakest of your 6 options. She also gives you the longest deathbomb reflex time (In Touhou games, when you get hit, you have a split second to bomb and save yourself. Reimu gets a little extra time.) Reimu gives Sakuya A does nice damage, gets 4 bombs, but is a little more difficult to control, and doesn't give you as much reflex time.

I'd say I'm moderately decent. Why?

but i was too late

None other.

A countryman of yours contrived it!

That would just be awkward. O_O

Death by Kos-Mos's Miniguns isn't something to fear. It would be the most awesome and beautiful death one could ask for.
