I'm going to assume that since you're doing your homework before buying a product that you have already gone through the features information of both themes to determine which of these offers what you're looking for. There are some obvious visual differences between themes (which ultimately comes down to personal preference), with many similar features.
Support for all of our themes is carried out here in the AppThemes forums, and we have a large, active community, and a dedicated support team to assist our customers. We believe that whilst there may be many companies offering products for similar purposes, with similar features, sometimes all is not what it seems when it comes to actually using said product. The team behind the product is highly important, and being well established in comparison to other theme companies out there, means that AppThemes does offer what many do not/can not in terms of support and quality products. Another positive for ClassiPress is that is is highly customizable, with some great examples of what can be done with the theme in the
AppThemes customer showcase. We also offer a
marketplace where you can purchase add-ons specifically for our themes including additional payment gateways, child themes and more.
We do not offer installation or customization services, however we do have a
certified partners page where you can find developers for hire who are experienced with working with our products, and some of them also provide installations for a set fee. Thanks.
