The thing about titanium is if it is too thin it can feel a bit noodle-ly. So riding it may be important. If it is done right, it has kind of a springy spriteful ride that is similar but lighter to the feel of 853 Reynolds or True Temper OX TIG welded steel bikes.

That Bob Jackson looks fantastic, I wouldn't change a thing parts wise except for comfort, and I bet it rides fantastic. Lugged bikes have a great feel, like the miles disappear down the road.

I would really ride both to find the better fit.
