You can't judge the success or failure of ANYTHING by the podcasts app (except the podcasts app itself, of course).
Remember old QuickTime with wonky drawers and knobs everywhere? Everyone hated it, and rightly so, and switched to alternatives in every case where they could.
I really like the three “wheel” picker on iOS (used for dates, at least): for coarse changes, I “flick” the wheel a couple times and let “inertia” do its work, then I fine tune it when I’m close.
