Either way, the care and feeding is the same.
NiMH hasn't been used in years for consumer electronics because the power-to-weight ratio isn't up to par with Li-Ion and LiPo. (NiMH is still common in cordless phones, and rechargeable cells like AA batteries, but not in a cell phone, laptop, or tablet.)
NiCd was out of style when NiMH showed up, so it's all but extinct now. (Again, some cordless phones and old rechargeable cells still use this chemistry.)
Lead-Acid is what's in your car, UPS, and other large-scale, low-maintenance, low-duty cycle battery applications. It's not something you'll ever find in a portable device. Lead is heavy, can leak, is not meant to be used until depletion, and exhausts explosive gases during charging. I'm not really sure why it's even mentioned in this article except for completeness sake, because it's not relevant.
