GravityForms are probably one of the most known, and respected forms plugin providers. As a testament to that, I have had a paid membership for GravityForms since 2010.
The only thing I can say in terms of what to watch for – is that GravityForms to WordPress forms is like ‘Microsoft Word’ to word processors – they can do everything! However, sometimes we just need a simple text editor.
If your needs are simple, I also recommend Contact Form 7 – and I’ll do a quick demo and write up on that soon.
But if you want super flexible forms, conditional logic, subscriptions, addons payments, membership… GravityForms is for you..
