By using 14 different versions and parametrizations of a proximity potential and two new versions of the potential proposed in this paper, we perform a comparative study of fusion barriers by studying 26 symmetric reactions. The mass asymmetry eta{sub A}=((A{sub 2}-A{sub 1}/A{sub 2}+A{sub 1})), however, is very large. Our detailed investigation reveals that most of the proximity potentials reproduce experimental data within +-8% on average. A comparison of fusion cross sections indicates that Bass 80, AW 95, and Denisov DP potentials have a better edge than other potentials. We also propose new versions of the proximity potential as well as Denisov parametrized potential. These new versions improve agreement with the data.
