Theme suggestion for better UIUX

Hey, I am a newly graduated and wanna build my career in blogging, I have not enough knowledge about custom coding languages, so I want to use pre build theme for my blogging sites as UI UX is really important for better optimization. Meanwhile I am using Generate press which is good and am using for 3 months, but my site got rejection from Adsense, so I want to change theme, I need your suggestion on which I should move on, which is simple to use like just drag and drop or just import demo. I can buy it from here.
Thanks
