Hello,
In my opinion long-term you would benefit from a PhD, although competition is tough at all levels in pharma.
Without PhD you might land a job faster (for example in small biotech) because you cost less. However, progression will be slower and it will be very difficult to do a PhD later on.
This is what prompted me to a PhD...if you don't do it when you are young it is hard to get one later in life, although not impossible.
Thank you
