Tabular sheet music is much easier to read initially as it provides a one to one mapping between the visual representation and the physical location of the notes - i.e. 5 frets along on this string. However, from my experience there is a cap on the 'bandwidth' at which you can sight read this. It is just too hard to mentally parse a bunch of numbers on lines and turn that into notes when playing at speed. (For non musicians, 'sight reading' means to read the notes and play fluently at the same time)
Traditional sheet music has a steeper learning curve, however, I've found that reading this music becomes much more subconscious with practice and the bandwidth at which you can parse the notes is much higher. Also, it is much easier to notice patterns in sheet music - i.e. a major 7th chord in the key of the song is visually obvious no matter what the key.
