Are glass thermometers more accurate?

Liquid-in-glass thermometers without mercury are not as accurate, so they should be used when less precision and certainty is acceptable. However, analog alternatives, liquid-in-glass thermometers, and bimetal thermometers are the most economical options, with prices, as of this writing, often under $50.
