Unless you're being ironic. I didn't think much of those links tbh, a lot of them are just low quality freestyles??
Lil B is a troll, an entertaining troll. Same with Riff Raff.
RVIDXR KLVN are okay. They aren't great rappers, but the production is cool. Even if it is just rehashing the Memphis sound of the 90s.
Green OVA have some jams. They've slowed down with putting out records lately because even they admitted they were just pumping stuff out with no quality control and were writing terrible lyrics because there were trying to take the Lil B route and put out 100 mixtapes a year as their marketing plan. Of course everyone ignored the ACTUAL QUALITY of the material because they were caught up in the hype and jumping on a new artist before anyone else.
They've definitely improved over the past year or so though. Here's their latest video -

http://www.jimmyness.com/2012/06/shady-blaze-interview.htmlThe thing about most of these guys is the internet jumps on them while they are still developing as artists and thus their releases tend to be mediocre and surrounded by hype before they actually have the time to get better. Green OVA recognized this, which is commendable. I can't see RVIDXR KLVN sticking around for more than 3 years, especially once the chopped and screwed trend dies out. A$AP stole their sound, and did it better.
Action Bronson's album is one of the best rap projects of the year imo - http://www.livemixtapes.com/player.php?album_id=16558
