Buck Boost recommendation for 1Amp 5V from batteries

[Stonent]

I'm thinking of building a portable device with an embedded Raspberry Pi and LCD.  I'm not sure what kind of battery I want to use yet, but I'm estimating I'll need a continuous 5W of power to keep things running.

I'd like to be able to work with a variety of over and under input voltages (We'll just say 1.5V to 12V). So that would give me options of NiMH batteries run completely flat, parallel or serial connected 18650 batteries, or a LiPo pack.  (If I go lithium based I'll put in a pre-made battery protection circuit.)

I don't plan on integrating charging into the device itself and plan on getting a Nitecore charger for that. http://www.nitecore.com/productDetail.aspx?id=115

I'm looking for some recommendations for a through hole part that could handle the task.

A parametric search on Mouser for that range in through hole gave me these 4

MC34063
MC33063
MC33613
LM78S40

Would you recommend one of these over the other, or are there other through hole devices I didn't get on my list that you'd recommend more?
