Rarely. A large set is usually priced around the two or three bits you would have bought individually, and the rest are profiles you will never cut. Buy single bits from a maker who sells them singly and stands behind them.
Sets are attractive because the price per bit looks tiny. That number is only meaningful if you use them.
What is actually in a large set
Two or three straight bits, a rounding-over bit, a flush trim bit, a chamfer, and then a long tail of decorative profiles from a catalog nobody has consulted since the nineteen-eighties. Roman ogees, classical coves, edge beads. Most workshops use four or five bits for years.
The quality question
A set at set prices is made to a set price. The carbide is thinner, the grinding less consistent, and the bearings poorer. On a decorative bit used twice that hardly matters. On the straight bit you use every week, it does.
Where a set does make sense
A small starter set of genuinely common profiles from a reputable maker, bought to find out what you actually reach for. And matched sets that only work as pairs — tongue and groove cutters, rail and stile sets — where buying separately is not an option.
The better strategy
Buy the bit for the job, each time, in 1/2 inch shank where the router allows it. Within a year you own exactly the bits you use, all good ones, and you have spent less than the set cost.
Store them properly, and they will outlast several sets.
