I've always used the Astra theme but then I have the lifetime Mini Agency pack from Astra/Brainstormforce and so, of course, going to use it now. Astra theme is very good especially if have the Pro version. My design is not the best haha but the theme has a lot of custom options available.
Astra theme is very good I agree. But they then spoil it by lumping in a number of plugins which slow it right down. If you use the theme without any plugins then it’s a winner. But then again, many of the free Wordpress themes are just as good.
