Quite different, basically no gui. I like ledger better. I have my personal and two different business accounts using ledger. I use git to VC the data files.

Quite different, basically no gui. I like ledger better. I have my personal and two different business accounts using ledger. I use git to VC the data files. I've done quite a bit of scripting to make the system more convenient (automate billing, tracking inventory, converting between cash-based and accrual reporting). Ledger is really quite simple. The core of it could be implemented pretty easily (witness the number of "ledger" clones). I have my own somewhat compatible ledger program written in Python. It's crude otherwise I would release code.
