If you love technology, the new place offers it, and the old place doesn't, then that alone is a good reason for moving. You aren't causing your vested options to lose value by moving since your current employer sounds like it values marketing and sales more than technology. The only thing keeping you are 1) inertia and 2) the move and remote work. (The hiring probably doesn't compare to the much bigger pool of engineers at the new place.)
Unless the move and remote work are incredibly important to you, it sounds like an easy choice.
(One thing you haven't mentioned is big company vs. startup. Think about that too.)
