The neck heel is sufficiently different on NT and bolt-on that even with the same profile, I got a different impression picking one of each up and playing it.
For me, the Thumb 5 is very "Warwick" in NT format, and not so strong in bolt-on format.
I'd go after a streamer LX or (if possible) fortress over a Thumb BO, but I'd usually take a Thumb NT over any of them.
