I love Thrive Themes. I will admit to some overwhelm, though, because I am a member and so I have access to the entire suite of plugins. They are planning to come out with a tutorial that will take someone from A-Z in building a website and I cannot wait. They have great tutorials for their plugins and features; I just need one that takes me from the beginning to the end quickly without overwhelm. I find that I get overwhelmed more easily these days.
Apart from Thrive, I’ve only used basic WP. I’m still new to the whole website building thing, because every time I start afresh, life throws a massive curveball my way.
