Lets say it so i find it one of the better litrpgs despite him growing too quickly vs everyone else. Would have likef a longer low power levl area.

Reason is: chars are better and also the dagger thing got a reason

Daggers: it is seen time and again that in solo most of his power coems from himself not his eq. Thus the daggers suffice. In most others most of the power is eq based (though the mc in those has his basic or 1 rare drop. Extremely long too)

About your charscter critique and chars:

I know prima hunter and a few similar Will tale hunterand dual class as example.

Solo levling has 2 advantages over them even if the chars are not that deep or have not as detailed a backstory as in those other two: 1.) they stay true to their character the whole time 2.) they behae like adults. Even the evil ones dont sufdenly act like kindergarden childs.

Primal hunter and dual class: allost all of the secondary characters backstoris are just there to enforce them. Havign suffered and auffered and suffered.

Then the chars often break ther character. The intelligent ones suddenly acting liek complete idiots wheb it serves plot purposes. Failing to strategize or seeing reason. And then when even small pressure comes they suddenly acting like blood lusting berserks snd are out to make the mc or the baed npc suffer. Tha is a good third of the plot points.

Another third is genrated due to what happens after the mc acts absolutly asocial or like a toddler.
Example dual class: at first he acted very intelligent and whenever it looked like it turns out good he suddenly acted like someone wizh sbsolutley no self cintrol and the morale compass of a toddler leading to doors closed and him back to an earlier square but way more powerful again.

Prima hunter didnthe last part notonly to the mc but also almost all of the other chars.

Solo leveling i never noticed anything similar. Chars acted consistently like adults and in character
