Which TB Safety?

I have Winfield, but I'm concerned with his 1 solo and one PD this week. If Smith is playing more in the box and in the slot, is he a safer play?

I like Tykee more than most, but Winfield has proven he's a DB1 year in and year out and isn't reliant on box snaps to do so. I had the same dilemma in a league and stuck with Winfield.
