the story of solo level is complete. if you liked the first season and want to know whats next, you are going to watch it, whether if it is good or not is a rhetorical question. seems you did not like the 1st season or the story of solo level, so why ask if youd like the sencond?
It does move quickly, but IMO it doesn't feel rushed. Anime so far feels rushed. Manwha hell castle took limke a dozen chapters. Only 2 real episodes for the Anime. That's a little bit more than just "moving quickly."
I love it, but one thing changed, in the first season I was more afraid about the protagonist. In the second season everything feels like it's to easy and he is overpowered anyway.
