Digital vs strips?

Wondering who uses what for opks! I have a digital clear blue that I've been using and gave me a positive last cycle however AF came. Those sticks are expensive so I have some strips too. I've been doing both at the same time- digital has been giving me "low" readings and the strips look almost positive to me. I like digital bc it's more cut and dry and the strips confuse me...but just hoping one or the other isn't missing something!
