Most truck preferences are silly. Not riding Slappy cuz of the name isn't much different than everyone flipping about Indy moving to China or claiming Ventures don't turn because they rode lows one time in 2002. I have avoided Slappy because I just don't want more truck madness, but the branding is one reason why. KP clearance on Venture and Indy don't limit me and both turn and grind fine. Every truck has its limits and sometimes I pick to ride something based purely on how it feels or my mood. Indy is a corny brand, but I really like the way they skate and never have issues with them. Slappy doesn't offer me any upside except ditching the Indy branding, but I do so for one that has branding that I personally feel is corny. They went the "lets give these to ppl on social media to grow the brand with pseudo sketchy reviews" approach that Cariuma did. While core shops carry them now, the early push to be in only large shops and Zumiez was kinda gross. With Ventures I have brand nostalgia and like the team and image.
None of this bullshit helps me skate, but having a setup I vibe with makes me content to skate and not think about shit. When I was always in pure madness mode mixing dimensions or graphics or trucks from brands I didn't like I never really felt excited or content with my board.
