Many swear by silicone caulk. By all accounts it does last longer and it sticks better to the surface.
But then why do I prefer acrylic caulk?
I prefer the acrylic because to me it has a warmer feel to it. Somehow the silicone caulk seems cold and sterile like a hospital environment.
And I feel the acrylic can be laid more neatly. Silicone is touchy. Ever see the sloppy mess in a public restroom? Silicone for sure. If done by an amateur, the results are absolutely terrible.
Ask me for a sample of both to compare so you can see what you prefer.
