I find it difficult to give a fair assessment as different consoles excel in different areas of their specification and commercial factors also determine performance.
I've yet to see the Switch offer many of the large ambitious games that we got on ps3 and 360 because the developers that developed those games have moved onto later more powerful hardware. The Switch is in a position of getting great Nintendo games and a few weak ports of third party games often by sub par developers. Also Switch has pressure to keep cartridge sizes small and not take up too much flash memory. PS3 and 360 had larger hard drives and cheap optical storage.
Dual layer PS3 bluray discs offered 50GB of storage but that isn't really viable for a mobile platform. Clearly the Switch is more powerful but that doesn't mean we should expect to see more ambitious games than ps3 and 360 the third party games will likely be smaller games or conversions of old ps3 and 360 games plus weak xbone and ps4 ports.
So my point is it doesn't matter in some ways if the Switch is more powerful because there are other factors in play that will prevent it getting the wide range of ambitious titles that the ps3 and 360 got.
Not forgetting there are some pretty decent graphic intensive games now for Android, IOS and windows tablets.
There are a lot of impressive games on a lot of different systems and many game genres can now be done very well on even quite cheap hardware.
