I tried them both and went with lockdown
I like the graphics allot more on protect but I trust the dev more so I'm sticking with lockdown.
Even Elias is a very trusted dev. With tweaks like SBRotator, Callbar, AudioRecorder etc. and I have been following him a long time too. But, I think Biolockdown allows you to lock down even settings which are not available in protect AFAIK...
Yeah it does that's primly the functionality part that won me over. I'm not worried about the apps other than eBay and AppStore, daughter already accidentally bought a few thing- lol
But nothing us more aggravating than someone playing with wallpapers and brightness you know
