First, welcome. Second, congrats on that MBP! Nice machine!
I share your concerns about SSDs over the long haul. They definitely have a few advantages over platter drives, but my Spidey Sense just keeps telling me that the technology is not yet mature.
Which is not to say that SSDs suck, just that I have a hunch big improvements in them are just around the metaphorical corner that will address their biggest problem, which is as you say write speed.
That said, computers do a LOT more reading than actual writing, which is why SSD has been successful in the market in the first place.
If it were me, and the decision had to be made today, I'd favour platter drives because they are inexpensive and reliable (and easily backed up).
A couple of years from now I might well be saying something different.
