For me Switch and Nintendo DS are neck to neck and it varies pretty much daily what system I prefer.
Switch obviously have a lead when it comes to the power but the battery life of the NDS made it possible to play for the whole transatlantic flight and bus transfer. The lighter weight of NDS made it easier on the wrists during longer playing sessions while the switch feels a bit heavy at times.
I think the original games for NDS was more innovative and different, but the amount of quality content on the switch is just unprecedented on a Nintendo system.
Would probably rank the handhelds as:
NDS Lite
Switch
Other NDS models
GBA
GBC
3DS (sue me, dislike the thing)
GB
