The way I do it when selecting opamps, is to write an Excell spreadsheet and each row list the performance parameters that are important to the application itself.
For instance, if your current source must handle high frequencies, I would put slew rate first. If on the other hand, I'm dealing with sub-microamp currents, I put low Ios parameter first.
Select as many as you require. And as part of the selection, the IC package, cost and availability may play a significant role.
Then in the columns add as many opamps from as many vendors as you want. Open up their respective datasheets, and write down the values of each performance parameter for each opamp.
It is a lot of work, but when you are finished, you'll have a nice table where you can easily compare all the requirements. Your requirements. Only you know what is needed.
I've many times offered suggestions, to have a reply of "its not available in my country", or "I can't solder SMT components".
