The strength of an enhancement is not in the adhesive or the tip, it's in the structure of the overlay by placing the stress point and spine in the correct place, so most adhesives are on par with each other. Obviously there are thicker viscosity ones, brush on ones, tubes, etc. I used to love CND GelBond as it was thick and great for ridged nails, etc. but they don't seem to stock it anymore. I use NSI Polybond now.
