I haven't ridden a transcend since 2010 the 2009 Platinum and rode the absolute as well I am on a Watson Hybrid for the parks for two seasons and have ridden many LF boards like the classic etc..
IMO theres no way to compare these boards they have significantly different rockers and ride different.. Most LF boards are light fast and have smaller rockers so pop is more created through the rider and fits more styles and varys..
The transcend is a huge 3 stage rocker, is slower than LF models, and is made for riders who ride more Wake 2 wake and like the upward more then outward TYPE OF POP AND TRICKS..
Im not sure how much has changed since 2010 on the transcend but that's my opinion. Take it with a grain of salt..
the S4 is my favorite boat board but on a Bside right now but will be going back to LF because they fit my style behind the boat more than other Brands.I do ride HL systems for boot set up so its not that im stuck on a brand I ride what works for me..
