I do not think I can recommend Appcelerator at this point due to the issues with Appcelerator studio, lack of good debugging support, lack of thorough documentation and forums and the additional cost overhead of licenses. The pros are just that it allows for cross-platform development. However, Cordova does a much better job of it and excels at places where Appcelerator currently struggles
If you have any problems with your rankings or a decrease in ranking position within google it is very good to make an Link Audit with the Link Research Tools. Then you Screen all Links manually and setup your disavow-file easily. With the Link Detox Boost you gain Rankings back so fast. The last time we used it for a client, we got back the rankings within a week to 170 Positions within the Top Ten, even Position 1.

It is very hard to debug your code. Breakpoints never worked for us even with the latest Appcelerator Studio and we had to rely on log statements to debug.
There is a need to purchase licenses from Appcelerator to run the code on a device or for creating iOS distribution builds. This is an additional cost when you have already paid for Apple developer program for precisely these things.
If things are broken due to lack to support between Appcelerator and a new iOS version, you pretty much have to rely on a new version release from Appcelerator for the issue to be fixed.
It is difficult to create enterprise distribution builds where the distribution certificate is owned by your organization's team and you only have a development certificate for the same.
The forums on developer.appcelerator.com are seldom helpful. It is hard to find solutions for issues even on other forums like stack overflow.
Appcelerator makes you write a structured code whereas Cordova just packages your code and you are free to structure it. Appcelerator bridges your javascript code with native code and that would make it run faster than javascript code in Cordova apps. However, with recent mobile browsers, you would hardly notice any performance deterioration with Cordova apps. Appcelerator struggles with issues related to its IDE, debugging, documentation and forums and additional costs. Cordova makes it much more simpler to develop cross-platform apps with better developer support, debugging support, documentation and forums minus the additional costs.
LinkResearchTools is much more advanced in analyzing links. Period. All the other mentioned tools have many useful features for SEO but LRT is definitely the way to go for backlink analysis, link building, and competition analysis. They also offer very nice and quality courses for improving SEO knowledge. I already attended one of them and I am very satisfied with the knowledge I gained.
We were able to build and deploy a mobile app with Appcelerator. However, the platform still has issues and does not cover our needs as much as some of its competitor like cordova does.
