[DBZ/DBS] Are there any practical/tactical/strategic difference between the beam attacks used by the different characters?

Beams seem to be pretty universal, and although they usually have their own name and hand movements to go along with it they all seem essentially the same. Are there any real differences between them? What differentiates a Final Flash from a Galick Gun from a Masenko from a Kamehameha other than the color and name? 

Some characters like Gohan (Masenko, Kamehameha) and Vegeta(Big Bang/Galick Gun/Final Flash) know multiple beam attacks so how do they choose one over the other in a given situation?

More than you think, but not always vastly different.

The Kamehameha for example is patient, powerful and effective, like a turtle coming out of its shell it's slower but it's a strong technique that is rivaled by few.

The masenko is similar but much quicker and easier to cast, good for beginners, Piccolo develops the special beam canon as a means to combat the masenkos weakness vs the Kamehameha, it's also more piercing like a sword than a lot of other ki attacks. But it takes longer to charge. Not to mention it seems to have electrical properties. It's channeled and charged differently.

Vegeta's galick gun is similar. It's a quick and powerful attack, the big bang attack however shoots a large ball that explodes and leaves a cloud in its wake. It's also slower. His final flash takes awhile to charge but is immensely powerful, to the point that there might be diminishing returns on its power.

Krillins signature the destruct disk values sharpness and can catch unexpecting opponents with its blade. As almost happened to nappa.

There are tons of ways ki can be applied. And they all play into the fighters strengths and personalities.
