We have lost so much since the skill and art of reading and playing from figured basses died out. Now almost every baroque sonata that is played is similar to every other because the same edition is being used and the spontaneity and creativity is gone.

And it's so annoying when editions not only supply realisations of the continuo part, they omit the figures! When this happens, I resort to using the bass part and pencilling in figures. (That's not a bad way to practise working out the figures, as well as studying already figured bass parts. If you're doing the latter, make sure it's a well figured bass - Telemann is often a very good place to start.)
I know the skills are similar, but I find using figured bass much easier than jazz/pop chord notation - I think because jazz chord notation doesn't relate the chord to its function in the harmonic context. I suppose, thinking about it, neither does figured bass really, but somehow for me, I find it easier to think about chord progressions with figured bass - things like chains of first inversions, cadential 6/4 5/3s etc.
The two pieces of advice I'd give about figured bass is that it only really makes sense when you've got a reasonably good grasp of harmony and chord voicing, and even more when you can apply that knowledge in practice on a keyboard (and preferably an organ or harpsichord in an ensemble!)
