I've had various tuners in my life, for a multitude of electric, acoustic and bass guitars.
I'm probably a cheapskate which is why I've always only purchased affordable tuners. All of them always had some annoying quirks, or were slow, or just straight out wrong on a certain string, etc.
This one just works. Always. Period. Just get this, forget all the other crap, do yourself a favour.
The only thing I wish it had is rotation, since some of my guitars have a strange shaped headstock (and/or I have pick holders on the back), which means sometimes I cannot easily make it face me when clipping it.
Totally recommended (in case it wasn't clear...)
