I currently have the Custom V, but previously had the TRS BTX. Construction wise and durability goes to the Burton. The biggest issue is the plastic tips on Lib. Its supposed to help with impacts, but really all it does is get damaged. If you can watch out for it and be careful with it you shouldnt have any issues. Mine had a nice little cut from getting hit in the lift line. Other than that the board held up with no issues.
Riding wise goes hands down to Lib. Its was the most fun board and held an edge better than any other board I have ridden. I would love to have one again, maybe the 57 instead of the 59 this time. A lot of people complain about slow bases, but I didnt have any issue. The board was fast, loose and stable when on edge. I prob the minority here, but I say buy the TRS.
Btw, I also rode a Banana a few days, but wasnt too stoked on it. I liked the TRS a lot better.
