Is it recommended to drive a pickup truck, or a four door sedan? I'm not talking about the "hyper-fast" version of a sedan that I've read about (where it can do 0 to 60 in under 4 seconds, has a top speed of 300 mph, and can stop on a dime), but for common everyday usage?
What do most people use for their driving needs?
Hopefully you're catching on to my analogy. The point is that it is impossible to know what wallet (or vehicle) will be best for someone without knowing more about their needs.
In the case of a vehicle, does the owner have children? How many? Additional cars? Do they need to haul heavy items frequently? Do they have any need to tow a trailer? Is fuel economy important to them? etc.
In the case of a wallet:
What operating system do you use?
How much disk space do you have?
How much patience do you have to wait for a wallet to initialize?
What level of technical skill do you have?
What else do you use your computer for?
Does anyone else have access to your computer? If so, do you trust them not to take your bitcoins?
Is it portable or a desktop computer?
Do you have a need to access your wallet from multiple devices?
How likely are you to maintain a regular backup schedule?
How important is it to you to be a fully participating peer on the bitcoin network?
How often do you expect to be receiving transactions?
How quickly do you need to know that you've received a transaction?
How often do you expect to be sending transactions?
Are you likely to forget a password if you haven't used it in a while?
Are you likely to use an easy to crack password due to fears of forgetting a complex password?
How devastating would it be to lose your bitcoins to theft?
How devastating would it be to lose bitcoins to user error?
Those are some of the questions I can come up with that would help determine the best choice of wallet. All of the popular wallets are used by many people. That's why they're called "popular".
If you want to do your own research and choose the best wallet for yourself, I'd suggest looking into these:
