The protection offered will depend on what is connected downstream from the receptacle.
I usually install a surge protector as the first outlet on a string and my customers have not reported any surge related problems when plugging in electronic equipment downstream from this receptacle. However, all bets are off if a vacuum cleaner or other motor load is plugged in downstream from the surge protected receptacle.
I have also installed a surge protected receptacle at each point of use when the cost of the equipment and/or downtime warrants it. You'll have to weigh the cost of the equipment versus the cost of the recptacles & make your own determination. When I was working for a fairly large bank in this area, I convinced them to put in a TVSS receptacle at the point of use for every computer terminal & teller machine. Their savings on repair bills for teller machines alone more than paid for the receptacle installation in less than a year.
