I would look with suspicion at all current estimates. In my lifetime, which luckily does not reach back to Einstein's original papers, I have seen serious values for density, assigning the critical density equal to 1, that have ranged from less than .5 to more than 3. Esthetically, it would be nice if it was 1, but I think it's still wait and see. And the value shapes so much of the rest of cosmology . . .
