Given a choice between the two, I would prefer the 4.8V version. NiCds are very reliable, very durable, inexpensive and last for years without worry.
Actually, I second that.
Also because I see little reason to use high-current release batteries like Lithium (LiPo / LiFe) to power a device that draws mere 100mAh - 350mAh in mixed use.
And ... the "single charger" argument doesn't cut it for me either because most decent modern chargers will happily charge your NiCd/NiMh ignision battery on one output
while they charge your LiPo/LiFe receiver batteries through another output
