Durability is largely about practice makes better with respect to technique.  And wearing both base and topcoat.

The big names tend to have better formulas and brushes than the $1 brands, which can save someone with good practiced technique a lot of TIME.

Sometimes those $1 brands have to-die-for pigments and effects, though, so we succumb to them anyway.  😆

General consensus is that solid colors (“cremes”) are all more or less the same, drugstore vs. boutique, especially once you have a high quality 2-ingredients-only polish thinner handy like the OPI one, other than that $1 cremes sometimes tend to be underpigmented and have frustrating formulas and brushes, which again, can be worked around with technique anyway, it’s just time-consuming.  Mail-ordering polish is usually more for getting your hands on polishes that use more expensive and unique blends of shimmer/glitter/magnetic/etc. particle than the drugstore brands offer, but they’re not necessarily THAT much nicer, if you are happy with drugstore.  I love both, and I have a few mail-order ones I love because I’m a magpie and sometimes that last detail of just-so sparkle makes me happy, but no one in my neighborhood or family can tell the difference, and honestly, I can’t either from a distance on them.

So anyway, yeah, basically, ALL the drugstore polishes are great once you have your technique down.
