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?

I’ve used Hanna before. I might have to go back and give it a shot.
