So, I'm a nail tech in Boise, Idaho. I literally have women come in all the time and I'm ask them if they want Gel Polish or Regular Polish, most of the time I'm crossing my fingers hoping they will say Gel Polish because as a nail tech by the end of the appointment we don't want to sit their and wait for your nails to dry, regular polish is a pain in our ass.
Regular Polish
Pros
you can take it off with polish removerCons;
it smudges
long drying process,
chips easily,
doesn't stay as long
glitter with regular polish is rough and will come off a lot easier and faster
nail art is impossible and turns out not as pleasing to the eye as one might think.
Gel Polish
Pros
Dries in 30 seconds
Last Longer
No Chipping
Glitter stays longer and feel smooth, no roughness
Nail art looks flawless
Cons
If removed improperly by a nail tech or yourself, the nail beds can get ruined but it's not the gel itself, it's how its removed.
