Most reliable pregnancy Test?

What's the best pregnancy test to get heard mixed reviews. I'm currently on first day of missed period, although this is not exciting me too much as some months my period can be a day or two out of prediction but last month and month before were exactly the 24 day cycle to which today is the 24th day and when o should see AF.. I don't feel my normal AF symptoms as such either except a bad back so maybe this cycle is just gonna be a bit later.. Id Rather test for piece of mind.
