IMO big transformer adds weight, cost, possibly hum, and switchers don't while also supplying all the current needed and better stabilization for peaks.
To add to this, there is the common misconception that switching power supplies are noisier and can’t provide sufficient instant current. Both are incorrect. The best performing amps use smps suppies now, benchmark, hypex, purifi.
Using a linear supply for a hypex or purifi does not result in the best performance, but does let the builder claim a different and superior product, even if not true.
