Some popular cubes nowadays are basically the DaYan cubes (mostly excluding the LingYun VI and the Taiyan). A lot of people like the LunHui, but personally I think it pops too much. The LingYun VII is supposed to be a pretty good cube, too. If you ever get a DaYan cube, the 48 point edge mod is highly recommended, because it will make the cube a lot smoother and overall better (in my opinion). However, the FII is still a great cube, and some people still use Alpha V's as well. If you like the Alpha V, the FIII is surprisingly crispy, but I can't say I like that either.
And just for next time, could you try doing some research before making a new thread? There are multiple threads a week about "which 3x3 is the best," and if you just briefly used the search engine for this site, you could probably find some pretty recent ones.
