Selecting the right training and certification

Hi All.

I came from a development background and have been working with SharePoint for 3 years. I’m current on SharePoint Server 2013 enterprise. At the moment I administer our server farm but I also create apps using SharePoint Designer and the out-of-the-box tools. To be honest, I enjoy both (sometimes). However, there are increasing ready made apps from the SharePoint App store. 

My employer will send me on a course. What do you guys think? I’m not sure which route to take – developer or architect? Which route has the better career path in terms of earning potential?

Thanks, Larry
