Leave German for an American company?

Hi. I'm a SWE at a big German company now (in Germany), getting around 110k all-in. I have an offer from a large American company (not FAANG) (edit: full-remote from Germany) with 130k base + a one time 80k RSU (vested over 4 years) + 20k RSU refresher per year as bonus (but not guaranteed).

My work is relatively relaxed currently, very stable with amazing WLB (I work 4 hours per day). But I'm also bored at the same time and do not learn much. I feel I'm retired... with no career plan.

A benefit of the American company is that it is bery interesting personally and I will learn a lot, and it is full remote, but most probably i need to work more (and maybe less stable?).

What do you suggest? It's really difficult for me to choose. My gut feeling says "stay", but my "nerdy" feeling says move.

Edit: I'm in early 30s. I love traveling, so remote option is good. And ofc, more money is better.

Edit2: I don't plan to move to the US. I'll stay in Germany, and my teammates are in Netherlands/Spain/Poland/NYC.
