I mostly buy Avon or No 7 nail polishes. I am an Avon representative and I find the polish very hardwearing and they have really improved their colour selection in the last couple of years and bring out many more "on-trend" colours. I buy No 7 because Boots in the UK often do a free £5 off voucher, so I can pick up their polishes for under £2. I sometimes buy OPI because I love dark nail colours and they have a good selection. I own a few Chanel polishes that were given to me as gifts, but to be honest, I find my Chanel ones chip the easiest.
I would say firstly to look for the type of colours that you would wear or that suit your skintone and then buy one drugstore and one Chanel or another premium brand and try them out. You will then find out if paying more is worth it.
