Sxvector is the best (he knew it reason of why he never reuploaded stuff) he retired but the biggest reason was the harrassment he suffered on other site by a certain user named Ramon Garcia one that thinks editing a screenpack without mentioning who made all the code and claiming it your own work is the way to go. You know the mugen scene is bad when they start forgiving people that spitted on the community face. It has the same feel as the one's that inspired it. The guy who's probably making the best SP's isn't even releasing them to the public. My SP's basic.or 'retro' if we're being nice. So even if he'd been around, he still might not agree with that.
Someone who 'made the best screenpacks' is a subjective statement. This guy said he 'started to idolize the sp at the beginning of the pandemic.' It's likely this guy just showed up on the mugen scene, has no idea who Vector is cuz he's gone, only knows about mugen based on what he see's on facebook(like a lot of people really), learned what he could in the time given and produced a SP that reflects what he's gathered in that amount of time. It's obvious he borrowed from Vector, but it's different enough to be considered his own. It's really nothing new to use sprites, concepts and other things from other creations. Tbf, a lot of Vector's screenpacks look similiar.
