antenna help

Hello. I'm new to the forum so I will apologize ahead of time. I'm quite sure this question has been answered many times so bear with me. I was debating between the wilson 1000 and 5000 magnetic mount antennas. Then someone told me to look at the sirio 5000 performer antenna. I have a cobra 29 lx chr le radio (brand new). Flying J was clearing it out, so I got it for $30. I'm asking the forum which would be a better buy. All three antenna are priced within $10 of each other, so I'm trying the best antenna the first time.

Thanks in advance to anyone that can help...
