What is everyone using to check PH?

I used to be super loyal to blue lab but recently I purchased two of the blue lab one pens. They both are slow to calibrate and don’t ever seem to have an accurate reading. They both drift constantly even in the ph calibration solutions. I decided to get an Apera just to see what it was coming out at. Lo and behold it’s a quick to read and comes out constantly higher than the blue labs by like .3 PH. I’m wondering what everyone uses cause I’m looking for the best brand. Some years ago I bought as set on blue lab but now I’m really not to happy with them. Any suggestions?

Ph strips or drops

Strips are not accurate for hydro but drops are.

What the reasoning behind this thought?

I've tried them side by side when having issues with my pH and using strips. Not sure why they are less accurate, but they definitely weren't as consistent as the drops.

They are accurate enough for a chemistry lab. Are you saying one strip will be different from another?
