I am going to go to Germany and give it a try, taking it easy, and let you know about the updates from my side, wish me good luck!
If you would regret not aspiring beyond the TT position at home, then the postdoc is the natural option. However, you should most definitely not "take it easy" during the postdoctoral period. The first few years after the Ph.D. are critical in determining your long-term career trajectory, and you need to be exceptionally focused and productive during your postdoc period for you to have a real shot at a TT position at a research university.
Two years is much shorter than you might think, given the time to write up and submit a paper, and then have it be accepted. Note also that you'll be applying for a new position after only a year on the job, so you really want that first year to be productive.
