You ever try backspacing in sh? Bash is the one for me in all consoles I use.

I have indeed (and since a very long time ago) had backspace working in Bourne Shell (sh) - you may want to look at the command stty in order to set the erase character to be the same as the character generated by your backspace key. It is common to find that the backspace key sends "control ?" and changing this to "control h" often arranges the difficulty. The change can be done in your .profile file, for example.
I agree with you though - bash is a very good thing. Must be why they call it Bourne Again Shell. I've been trying zsh this last little while - but I'm not sure that I'm getting the best out of it yet. I'm looking for a good book on this one. If you know of one please inform.

never cared about installing anything except bash
bash does everything i need
it's what 99% of the world of linux uses

You might want to give zsh a try. I'm still finding my way with it, but my idea is that some things that you can do for yourself in bash come ready made in zsh. I'm maybe lazy, huh?

I heard a lot of nice things about zsh, but I haven't got around to trying it out much yet. So my vote this year goes without doubt to bash.

Bash got my vote too - don't have enough experience with zsh yet
