I have Stencil and Crello. I think Pixelied templates, UI and UX is comparable with Crello with different key features. Pixelied got my attention for its capabilities to upload and edit svg illustrations.

I am delighted to see the mock-ups for monitor/mobile devices too, it is a time saver for me since I no longer need to download the mockup and licenses again and again from Envato Elements for different project.

Looking forward for the 3D mockup!
