In term of price value and accuracy, I say the Kaizen T80 tracks.

Though, it has way more steps to do than other T80 track, take a lot of time, as they try to mimic the actual production of the track (which is the selling point for me personally). It is resin track with metal pins. The glued parts are in the middle of the track so it likely won't fall apart by time. So you probably won't have any problem. My main concern with it is the low to no stock almost everywhere.
