I'm 5'8" and 145-150 lbs. I have springs because that's the only way I could get a saddle wide enough for my sit bones. My outside sitbone measurement is wider than any of the unsprung saddles. (my sprung B67 is 210mm wide. )
However: sometime next spring Brooks will begin selling the B68 - which is my saddle WITHOUT SPRINGS!!! Whoopee!
Springs are good in that they do absorb a lot of the road buzz. They won't absorb big bumps, these are stiff non-bouncy springs. If you are lopsided, the springs let you even out a bit. On long rides the springs are great.
My saddle has black springs, and truly they are hardly noticable, especially when my saddlebag is hanging there.
The major downside I've experienced with springs is the noise. Not from the springs themselves, but from the seat frame. The springs allow the frame to twist a little, and that twist can get noisy. Wallbike has helped me work on the noise. With a lot of grease and care I've got the noise down to a faint ping every once in a while. That is a huge improvement over the creaking groaning snapping I had going for a while.
But, as one LBS guy said, the noise is the price you pay for supreme comfort. And it is supremely comfortable!
However, if I ever replace my B67 (Mimi has had one of hers for 30 years) I will replace it with a B68. See how I like no springs.
This is my road bike with a black sprung B67 Brooks saddle:

And this is my hybrid with the same saddle:
