I'm often using the BQ24074 as it also allows pseudo-MPPT for solar charging and load sharing to preserve battery lifetime.
Other Asian chips worth having a look: TP5000 and TP5100.
Yes the TI IC is loaded with features but will add a spike to the BOM. I like the TP5100 more mainly because it can support both NMC and LiFePo4 cells and hence i can reuse the design easily.
I started using 3-4S batteries with BQ25798+BQ77915, and it's great, although completely different category both in capabilities and price than what this thread is about.

Nordic's new npm1100/1300 are the shit for low power applications
Just be sure to read their errata and not buy the recalled ones.
Are there any you like that have options/config for lower charge endpoints? It seems like there’s only a market for squeezing cells to the limit.
It's TP4056, My Love....

I have been using the TP4056 so far. Saw some benchmarks when it comes to sleep power draw. Seems to be a quite good component.
