I think php has a gentler learning curve, but you still need the same level of expertise to get something decent out of the door. From the recruiting side it's still a PITA to find good engineers and it's reflected in the final cost of hiring. I might be biased, but moving jobs every now and then had more impact than doing php or ruby (the other contender would be nodejs, I think go and python tend to be used on different purposes or complementary to the web stack)
