I believe this question warrants a nuanced response. It depends on what you are trying to accomplish with your testing.
If your goal is binary understanding, such as "do I have ammonia or nitrite," then cheap tests (and even strips) are fine. I use API kits for this purpose. (Ammonia and Nitrite)
If your goal is to have a low fidelity understanding, such as "are my nitrates low, medium, or high," I also think kits like API, Red Sea, Salfiert, etc are good here. I don't use strips in this manner. (Nitrates in a FOWLR, pH)
If you need high fidelity, then Hanna is the #1 choice, and then something like Elos would be just below. (Nitrates in a Reef, Phosphates, Calcium, Alkalinity, etc).
I use Inkbird and GIDIGI for temperature. I also use GIDIGI for ORP.
I used a refractometer for Salinity. I used to use an Apex for Salinity, but that unit is almost 18 years old now. My cheap GIDIGI is so bad at salinity that I pretend that probe doesn't exist.
