I decided to divide all weapons into five different categories depending on their effectiveness.
One star weapon

In this category I have included all shooting weapon. It is very discredited itself in the previous parts of the game. As you can see, I almost never even used it (actually I did, but only in training missions and in the demo version). The main disadvantage of this weapon is a very low attack power, which stretches the process of killing a monster in half or two. Accordingly, it is not very tempting for a half hour run around for a monster with a bow, when you can handle it with the sword in 15 minutes. Another flaw: protection, reduced by half. I do not know why the creators of the game did this, but the shooting weapon that require the player to approach the monster (such as a bowgun) closer, can prematurely bring the player to the grave.
Two stars weapon

Two stars get a hunting horn, a lance and an axe. I gave such a low assessment for their slowness. Horn and axe very slow down the movement of the player and do not have a block. Make them some kind of trick so that you do not have to drag the monster with the speed of a snail, it would be better. And with a lance in this game a separate story. Imagine, you do not need a lance in this game! In the Unite and the 3, his presence was justified, but things change and now the lance is completely replaced by a gunlance. I'm sorry, lance, you really helped me on a trip to the G-rank Tigrex in the Unite, but your time has passed.
Three stars weapon

I must admit, Generations have finally improved the sword and shield, as well as dual blades in such a way that they can be used normally. And even more: you can go with them on high-ranking monsters. Sharpen the blade with a special composition, increasing affinity, and go ahead - conquer the tropical thickets of the Jurassic park.

Despite the seeming gentleness of the sword and shield, the monsters die very quickly. With S&S I went to high-ranking dinosaurs, with double swords to KechaWacha. Another three stars can be considered an old good stick with a beetle. I dealt with it with Seltas. But if you want to move on the game further and not be killed, you'll have to pay attention to the four-stars weapon.
Four stars weapon

Katana (long sword), hammer and charge blades. This weapon is well suited for further passage of high-ranking missions. The katana shreds, the hammer rolls over the monsters, and the charge blades is a mixture of the shield and the axe with two modes of action. Personally, I really like the hammer. In the first games of the series it was realy week, but to the Generatins they made a really powerful weapon. Yellow sharpening at the end of the game? So what? The main thing is that all the brains of monsters are knocked out! But the charge blades, although relatively new weapon, but capable of producing a series of deafening explosions, after which to hide the player from the counterattack of the monsters behind an impenetrable shield.
Five stars weapon

If there was a G-rank in the Generations, I would recommend a great sword and a gunlance to pass it. There is no G-rank in the Generations, but there are deviants with impenetrable skins. Therefore, only the universal great sword and gunlance can strike enough force to somehow touch them through the armor. And, importantly, both these weapons have a block, otherwise meeting with deviants would end very quickly. In the MH Unite and in the 3 both, the great sword and gunlance were the best weapons created to walk with them on the most difficult monsters: Rajang, Fatalis and Alatreon. In Generations, the effectiveness of these weapons has not disappeared anywhere. When the situation seems hopeless, think about the great sword and the gunlance - maybe they will help you go through the most difficult missions.
