I do think there are small differences between glues.
When you look at the MSDS of the glues you will notice that the more you get into the gel kind the lower the percentage of cyanoacrylate gets meaning to make it gel I assume they have to add other stuff. No idea what that other stuff might be or how harmful it is but I wouldn't want to be the first one to test it so I try and stay with tried and proven ones.
