For phosphate (or phosphorus), hanna is imho best on the market, period. Either the phosphate ULR one or phosphorus ULR one, both pretty much the same.
The alk and HR nitrate (0 to 75ppm, not listed) hanna test "eggs" are also good but other options are fine so it's not so much of a curb-stomping. Nitrate LR (0 to 5ppm, listed) is too time-consuming and not worthwhile.
Hanna pH meter is great, pH calorimeter (egg-shape) is utter crap.
I like the salinity meter but it's not much different from other options.
Hanna calcium is a pita and I'm not a fan. I've never tried the ammonia one.
Just my opinions, lol. Flame me if you must but this is my experience.
