Which breast pump is the best?

I'm a FTM also. attended the prenatal course recently and asked the lactation consultant (LC) to recommend a pump to me. she say that Spectra is not bad while medela is good, it's quite expensive. I initially wanted to buy hegen but she shared that Hegen's pressure to express is not as good but she ask me to go test it out.. all the mums in the class bought spectra so it kinda also tell me what to go for.. just my 2 cents worth 😉
