MODO's good if you don't need dirty rattly punk - I don't quite like how it does that. Ample stuff is good, its one big weakness being that as you go up the fretboard you get fewer velocity layers and round robins - good for acoustic guitar type stuff, not good for chugging metal high up on the low strings, so that might force you into using lower positions on higher strings for those notes. Shreddage basses are a lot like Ample without that weakness, but they all sound kinda metal - a good tone for some non-metal genres too (modern gospel, seriously), but for thuddy R&B not really. Haven't really tried others.
