Once you learn how one framework works, it becomes much easier to try out other ones. Most of them adopt similar patterns. Sort of like programming in general :)

If I had a recommendation, it would be to just stick to one for a little while, and then once you're comfortable, branch out and try to 'optimize your opinion'.

edit: and I wouldn't recommend any specific one. If it's the first one you ever learn, and aren't building any serious projects with it, honestly choose whatever the hell you want.
