I think Revman is the easiest to learn and work upon. You can also see CMA and open meta-analyst with reviewing tutorials.

Have a look at

and then something more recent such as

The simple and qualified software I recommond is "Metawin". However, if you need more complicated model (sevel predictors) and parameter estimation (ML or Bayesian), I thind R language could be your best choice. Most work can be accomplished with the package "Metafor", and it's free online!

These can be helpful.

MedCalc is another useful software. However, it is not free.

when you have used two different techniques and wants to compare the effect of the two in diagnosing a condition which meta analysis software is a better option

Uma Kailash I guess that Rev Manager is the best option to perform the meta analysis. @
