What are the best condoms to use? I keep breaking Trojans.?

I have been using trojan condoms now with my girlfriend for over 3 years, and not a single breakage, untill the other day we did it and it broke, it was Trojan her pleasure, I paid 16 dollars for a pack of 12, um is there any other better brand names and better quality condoms out there? like durex and life styles.. are they any good? Im afraid to use trojan again becase I dont want it to break again.
